Read Tony Bourdain's Kitchen Confidential. Lots of that in there.

I once got really frustrated with people asking me the phone# to our upstairs serving area so after the 50th time, I responded with 967-11-11 (the phone# for Pizza Pizza delivery)!!! Yes, they dialed it but only realized it just as they were dialing.
My previous director was gay and loved it. Every other day, he would come up to me and point out some guy in the crowd and say "Oh God, he is so cute/hot. That butt of his, I could just..." then I'd try to tune the rest. I got a little fed up 1 day so when he asked for a sausage for lunch (he meant it to be in a sandwich but never said so), I took the biggest debrazzini, wrapped it with plastic wrap, and dropped it on his desk with a packet of mayo and said "have fun!"
In baking, we "accidentally" made penis shaped éclairs. One guy overfilled 1 with cream and took it to a chick in another baking lab. She bit into it and got a face full of whipped cream. She also happened to be 1 of those girls who was very well known to all the guys in the program.
