KenJeongPenis

Bradley Cooper sat down to talk with Chelsea Handler on 'Chelsea's Big Interview Special' (Wed., 10PM ET on E!) , and the conversation naturally turned to penises. Specifically, Ken Jeong's penis on Cooper's neck in 'The Hangover.'

"Ken Jeong's penis on my neck was ... very normal," said Cooper. "Ken came up with that idea that day ... and I didn't realize it, but the part I play in that scenario, I get like, neck herpes from it."

You'd either have to be really good friends to pull this off, or never want to speak to or see each other ever again. The jury's still out on which category these guys fall into.
