*Pepto Bismol turns your poop black. Now I want to see a list of
   foods/medicines with the corresponding poop color.

   My favorite is taking MEGA-B vitamins to watch your pee turn a
   glowing neon yellow/green. Looks like Mountain Dew under a
   blacklight at a rave. I forget which one - I think it's B12 but
   it might be Niacin - I forget which one now
