This is the one scene that my wife retches at just thinking about.
We were in the US when the film was released and had just been for a meal before going to the cinema...I very nearly saw her dinner make a reappearance!
Might have been a TV episode but they had Steve-O eat the ingredients of an omelette, regurgitate them back up. Cook it, then eat it again.
I am literally retching as I type this.
