        |Lmao why is old Simpsons way more funnier than the new
        |Simpsons? I feel like if they did that in 2024 it would be lame

      |Holmes)???   I... yeah never saw that.


  |u/mr_lab_rat - 2 hours

    |u/SubstantialReturn228 - 3 hours
    |
    |Scrubs is pretty medically accurate


      |u/RoughBenefit9325 - 3 hours
      |
      |Very true but ever so often they fumble the ball. Plus it'll give
      |me a reason to talk about scrubs for more than 10mins!

      |Bambi...  It's ibuprofin...  You open their mouth and throw a

  |u/FantasticJackfruit51 - 2 hours
  |

|u/sikkerhet - 6 hours
|
|Mormons.  I've never been a Mormon.


  |u/faerieswing - 3 hours
  |
  |I know entirely too much about crimes involving Mormons.


    |u/sikkerhet - 3 hours
    |
    |why crimes specifically


      |u/faerieswing - 3 hours
      |
      |Several of the major news-making cases in the last few years have
      |happened to be related to Mormons. Lori and Chad Daybell (very
      |fringe LDS but all the murders were related to the end times
      |belief system), Ruby Franke and Jodi Hildebrandt, Kouri Richins,
      |Shana Gardner, James Craig, Tim Ballard, etc.


        |u/sikkerhet - 3 hours
        |
        |Yeah fair. I know a lot about Hildebrandt because her case
        |inconvenienced me specifically lmao


          |u/faerieswing - 3 hours
          |
          |Oh, interesting. How so?


            |u/sikkerhet - 2 hours
            |
            |It's very stupid.   I wrote a novel. The main plot of the
            |novel involves a child being religiously abused by an
            |authority figure to keep her isolated, which feels
            |necessary but is harmful to her in the end.  The main
            |characters were named Ruby and Jodie. The inconvenience is
            |that after working with them for a decade and getting
            |really used to them, I had to change their names in the
            |rewrite.


              |u/faerieswing - 2 hours
              |
              |Wow, what are the odds?! That’s so annoying for you,
              |though.


                |u/sikkerhet - 2 hours
                |
                |YEAH. IT WAS REALLY FUCKING ANNOYING.


                  |u/Burylown - 1 hour
                  |
                  |Idk why but that got a good cackle out of me


  |u/SquareGrapefruit3460 - 3 hours
  |
  |Mormon lore goes crazy. Joseph Smith could’ve been an amazing science
  |fiction writer


    |u/sikkerhet - 3 hours
    |
    |what do you mean could have been  his books have sold like a
    |million copies


      |u/SquareGrapefruit3460 - 3 hours
      |
      |Touché


  |u/_hieronymus - 3 hours
  |
  |Mormons.   Sadly, I was Mormon.


    |u/sikkerhet - 3 hours
    |
    |Welcome out. We have a hard time storing books but otherwise I
    |think things are better.


  |u/Only_Spare5063 - 2 hours
  |
  |Joseph Smith was called a prophet  Dumb dumb dumb dumb dumb


  |u/unintellectual8 - 58 minutes
  |
  |I almost liked this because I too, can give a presentation on how to
  |be a moron for 40 mins straight, until I read that closer.


  |u/Positive_Impress7658 - 57 minutes
  |
  |YEAH WTH DO I KNOW SO MUCH ABOUT THEM???


|u/User_reddit__ - 6 hours
|
|Books


  |u/Ihadsumthin4this - 5 hours
  |
  |Some may read into this.


    |u/C-57D - 3 hours
    |
    |I've seen their presentation, it's mostly fiction.


      |u/lungic - 2 hours
      |
      |Did you really, or are you judging the presentation by it's first
      |slide?


    |u/RAD_or_shite - 3 hours
    |
    |Fuck you, this was really good and I hope you're very smarmy, you
    |deserve it


    |u/victoriouspro - 5 hours
    |
    |😁✅


  |u/Background-Paint9479 - 3 hours
  |
  |I could give one of a book series. Either Lord of the Rings or the
  |Cosmere, or Cradle. 40 minutes would be easy


    |u/sonicmalley - 1 hour
    |
    |I could do one for each individual wheel of time book.


  |u/milk4all - 3 hours
  |
  |The depth of your reply doesnt give me confidence


|u/LongRest - 6 hours
|
|Warhammer 40k (I’ve never read any of the books or played but I did do
|a deep dive on the wiki one time. Also probably the history of pizza.


  |u/tyvanius - 4 hours
  |
  |It's crazy just how much lore is out there. I feel like I probably
  |know about 20% of it, but could still talk about it for hours.  By
  |the way, I started the Horus Heresy series recently, and so far it's
  |pretty dang good.


    |u/egyeager - 3 hours
    |
    |You'll want to use the Horus Heresy Omnibus project for approaching
    |the series IMO but it is well worth it. The series was written in
    |the most bizarre manner imaginable (kind of why it works too), so
    |the map is very useful. It also helps you zero in on characters you
    |might like to follow and focus on. I've been doing books with John
    |Grammiticus in them for maybe 6 books straight at this point and
    |it's awesome.


  |u/PokePotterfan93 - 3 hours
  |
  |I could give a passionate 40 minute presentation on why it should
  |have been called the Lorgar Heresy instead of the Horus Heresy. I’m
  |new to 40k and have watched way too many video essays


    |u/NoLawsDrinkingClawz - 2 hours
    |
    |Warhammer 40k: Why being even a slightly okay dad could have saved
    |a lot of trouble


      |u/PokePotterfan93 - 2 hours
      |
      |I still believe fully when Roboute Guilliman first woke up and
      |found out what had happened to the Imperium he had one or two
      |moments were he just thought. “I need some of the Space Wolves
      |hooch. This is worse than Angron’s singing.”


  |u/RAD_or_shite - 3 hours
  |
  |Oh yeah? Name the best toppings.  Then move onto the pizza stuff.


|u/zigthis - 6 hours
|
|The life, career, and death of Jimi Hendrix.


  |u/ibedemfeels - 3 hours
  |
  |Can we please talk about Stevie Ray Vaughn and his claim that Hendrix
  |was killed?


  |u/ObsiGamer - 3 hours
  |
  |A man of culture, I see


  |u/smileymn - 2 hours
  |
  |Same but for countless jazz musicians (Miles Davis is the easiest
  |one, I could talk for 40 minutes about only one decade of his
  |career).


|u/earth-ninja3 - 6 hours
|
|how to waste 40 minutes of your time


  |u/lemon-meringue-pie- - 6 hours
  |
  |Are you my boss?


    |u/earth-ninja3 - 6 hours
    |
    |yes. have a look at these graphs i graphed


      |u/Ihadsumthin4this - 5 hours
      |
      |No mention of any TPS report cover sheets?


|u/BrianPC94 - 6 hours
|
|The films of Paul Verhoeven


  |u/OfficerBarbier - 4 hours
  |
  |I'd buy that for a dollar!


  |u/PrestigiousWelcome88 - 5 hours
  |
  |Must include the phrases"Get your ass to Mars", "Dead or alive you're
  |coming with me", and ""Would you like to know more?"


  |u/MontyBoo-urns - 5 hours
  |
  |*Ackshually they’re satires!*


|u/Bloodllust - 4 hours
|
|World of warcraft


  |u/Vindicativa - 3 hours
  |
  |Oh God, I miss it. It's like I'm an addict because I can never go
  |back and/or just play it casually.


|u/LeavesOfBrass - 4 hours
|
|Abridged walkthrough of The Legend of Zelda: A Link to the Past. 100%,
|all items.


  |u/Atlv0486 - 3 hours
  |
  |60% of the time it works every time


|u/Asmodias1 - 5 hours
|
|How to lose your girlfriend to a guy and a girl at the same time. It’s
|a great Ted Talk


  |u/AAron27265 - 2 hours
  |
  |Yeah, I've got at least 40 minutes to spare


    |u/Asmodias1 - 2 hours
    |
    |My now ex dropped me for a different guy who used to be poly. Then
    |she discovered a like of women, and is now dating both. I wish them
    |all the best.   Lessons learned. I need to learn to be a better
    |partner and share the workload instead of doing it all.  Okay, so
    |maybe not that good of a Ted Talk.


|u/Romnonaldao - 5 hours
|
|It would take more than 40 minutes to set up the main plot of Warhammer
|40k to get to the explanation of why I like Orks so much.


|u/NotABirdWithWifi2 - 4 hours
|
|Organ donation and racial disparities in medicine


  |u/gatheringground - 3 hours
  |
  |Say More about organ donation.


    |u/joobacca1297 - 2 hours
    |
    |Slightly on/off topic, there’s a book called “stiff” by Mary roach
    |on body donation and it’s really really well done. I highly
    |recommend it


|u/Lyree93 - 3 hours
|
|I'm a history teacher, so I could waffle on about loads of things for
|40 minutes.


|u/extrabees - 6 hours
|
|Seinfeld or The Office lore


|u/SirVeritas79 - 6 hours
|
|My life as a miserable Los Angeles/Oakland/Las Vegas Raiders fan.   I
|could do a fucking one man show on the ways that franchise has FUCKED
|ME OVER for the last 39 years (and counting).


  |u/Xaiadar - 4 hours
  |
  |At least we didn't lose last week!


    |u/SirVeritas79 - 3 hours
    |
    |Yes, but that was only a short reprieve. I’m leaning in to the tank
    |this year. We need a QB desperately


|u/Haasts_Eagle - 4 hours
|
|Integers. And I'd be able to spend 40 minutes straight naming lots of
|examples of them.


|u/No_Roof_1910 - 5 hours
|
|Materials management, inventory control, production control.  I'm
|almost 60 and I've worked in manufacturing since my late 20's in
|positions like those above.  I've been a master scheduler several
|times, a production control manager several times, a materials manager.
|I was a production control manager in a Japanese owned auto plant here
|in the U.S. many years back, think 2010, 2011 timeframe.  No, I'm not a
|genius or even an expert, but I have decades of real world experience
|doing positions like these, and some of the plants and companies were
|huge too.  One plant had 1,150 employees, another had 750 employees and
|we ran three 8 hour shifts Mon to Fri and we always had shifts on the
|weekends too, though not always three 8 hour shifts.  One company had
|over 100,000 employees world wide in 40 different nations.  So, with
|decades of experience in this field, I could talk about it for 40 mins
|with no prep.  I've run and held weekly production control meetings,
|been in charge of conducting physical inventories in those plants year
|after year etc.  Again, I'm not some genius.  It's just what I've done
|for decades so I'd be able to talk about it is all.


  |u/Zlatcore - 3 hours
  |
  |Yeah, I feel like anyone who needs preparation to talk about what
  |they do for work is kind of in wrong line of work.


|u/DoctorTaco123 - 4 hours

    |u/lovelycapital - 6 hours
    |
    |Okay! But for that to make sense I need to start with this 40
    |minutes about vacuum creation.


      |u/pteridoid - 4 hours
      |
      |Okay, give us the two paragraph version, not the 40 minute
      |presentation.


|u/Sufficient-Berry-827 - 4 hours
|
|Sex trafficking/sex tourism/anti sex trafficking laws, the bias that
|exists within the mental health community with regards to domestic
|violence and SA, how IPV and SA stats are not very accurate and that
|bias is detrimental for men's mental health (not to mention most of the
|academic texts available on these subjects almost always use "he/him"
|pronouns when describing abusers), and why the Free Britney movement
|may have done more harm than good when it comes to the public's
|understanding of mental health issues and conservatorship.

  |I have ADD and I actually thrive in this environment for some reason.
  |Put me on the spot and I will spit out some bullshit that may
  |actually sound like it could be right, at least to those uneducated
  |on the subject.   I really really do not like talking to people. The
  |main reason is I always feel compelled to fill awkward silence or
  |breaks in conversation because I just can’t stand how awkward it is.
  |I’ve found the best way to do this is to let people talk about things
  |they are interested in, and then to ask them questions. I’ve also
  |found it helps if you are even a tiny bit familiar with the subject.
  |Because of this I make a habit of learning surface information about
  |as much as I can for anything and everything that interests me even
  |the slightest. I find I can almost always contribute to any topic of
  |conversation.
