I have a vague recollection of a recurring skit (from “Saturday Night Live” or a similar show) where a self-described “tough guy” and his girlfriend would encounter various people, and he would inevitably lose his temper and fight with them, as his gal pal would beg him not to hurt anybody (since he was so tough and dangerous – Ha!). Only he would not fight, exactly – he would collapse in a heap, or something like that. I can’t remember exactly what he would do, but he would wind up on the floor, thinking that he had beaten his opponent.
The first thing that came to my mind was that guy in South Park who abuses his kid for wanting to be a basketball player in their High School Musical parody.
Of course, that was obviously not the answer even before you posted.
