If you saw Trainwreck, you probably remember the super awkward yet hilarious sex scene between WWE star John Cena and Amy Schumer. While the two were getting it on, Amy asked John to talk dirty to her. However, he wasn't really the verbal seducer she hoped for. 

While the film was Amy's brainchild, John admitted to Larry King during a recent interview that he ad-libbed the lines during that scene.

“It was originally written different,” John told Larry in an interview you can watch below. “It was supposed to be an overly physical scene. Big guy, you know, ‘I’m sick of being with this guy because he’s too physical.’ And then we got into a room and we started to ad-lib and both Amy Schumer and Judd Apatow were so receptive to the kind of twist I put on the character that we ditched all the physical humor and just made it a very uncomfortable scene. It was very awkward, and at the end of the day, it ended up being pretty funny.”
