1. Greg Halstead, The Real World: Hollywood (2008)For the 20th season, the producers added a new wrinkle by letting fans of the show vote on the final cast member. Their choice? The king of all reality TV assholes, Greg Halstead. Dude was a snob who was obsessed with himself and walked around calling his roommates "peasants" on some 18th century Eastern Europe shit.
To top it off, he was a cornball. He'd play random corny tricks on his roommates and then steadily deny the pranks when confronted. Greg was eventually kicked off the show because he didn't want to be involved with the cast's mandatory improv class. Before he left, though, we got to see some sweet revenge when Will got some Becky from a chick Greg was seeing. It was a win for the inner peasant in us all.
