i think this was staged as a stunt. the bumfights guy got the kind of publicity and advertisement hes getting now through the spread of this video. his target audience is goign to be young people and those are the kidn of people who see youtube clips or would be attracted to pissing off doctor phil.
doctor phil got his publicity by making himself look good and kickign the guy off the show. he got a character boost in the audience's mind and also made some entertaining telivision.
win win situation.
