I used to work for a group of doctors, and once a month we would celebrate all the birthdays for that month.
One of the Docs that was known to be sort of "disgusting" and hard to get along with, had a birthday. Person incharge of ordering cakes had a joke cake made, a pile of brown colored buttercream fronsting poo, style. It even had a buttercream iced fly or two on it.
No one cut a piece, and the doc didn't even take it home. (Not that I blame him, I wouldn't have either)
No, I don't think I'd enjoy the toilet restaurant. "I'll pass"
Yuck. Although, once the office ran out of paper cups/glasses. We used the large urine specimen cups for the apple cider and donuts for the halloween party!
