The morbidly obese have a place in professional wrestling, and some big dudes might honestly surprise you. There was a wrestler named Roadkill who was a huge, fat fuck but he was well-practiced and could safely take large bumps.
This video is pretty good example of fat guys putting in work (if you don’t want to watch the whole thing, at least skim to the end where Roadkill falls off of the top rope onto some tables placed outside of the ring).
People like Jim are commonly used to generate cheap heat, get the crowd going by being obnoxious. In the promotion he was performing for in the US, he was given extreme liberties on the mic and even given the opportunity to wrestle a few matches. Jim’s role was originally valet, or a manager. He’d come out alongside a wrestler, or group of wrestlers, and get the crowd against them by interfering in the match. Jim could take a few punches and be dropped to the canvas, and that really should have been the extent of his participation. He’s not only a danger to himself, but others.
I am almost 100% certain the reason Jim moved back to the UK was due to their indie wrestling scenes. They are weird circuses. In one half, you have these really talented athletes going at it, putting on an intriguing show, but then you have the performative theatre aspects of it a la those showcased in Jim’s < 800k subscriber video. In the UK wrestling scene, you can be a “wrestler” by just being a total faggot, and the crowd will love you for it despite having 0 ability to actually wrestle. I remember watching this guy who went by Jack Sexsmith wrestle. Little twink looking dude, and all of his “moves” were provocative. What really shocked me is that one of his “moves” involved him pulling a live condom from his tights and performing the mandible claw (a la Mr. Socko for my fellow wrestling spergs). The condom went into the other person’s mouth. The crowds loved this shit despite how gross it was. I’m sure the crowd loves Jim and he feels really heckin’ validated by the UK wrestling fans. Asspats for squeezing himself into an ill-fitting costume and being annoying.
