Because, well, potty humor!
  1. Written on mirror above sink: the word "Stud" and an arrow. (Pointing to person in mirror aka you)
  2. Written on toilet cover dispenser: "Free disposable cowboy hats"
  3. Written on stall door for you to see while you're sitting there: Loooong arrow pointing down to teeny writing at bottom of door so you have to lean forward to read it: "You are now pooping at a 45 degree angle"
  4. And for the win: "One dark night, when the moon was green, around the corner came a turd machine. A shot rang out, a scream was heard, and a man was killed by a flying turd!"
