I've only ever seen ~45 minutes of this show (and they all aired last night. Someone broke down in tears and had to quit the show because their grandma died and the entire segment was presented as a five second-long cutaway at the start of an immunity challenge? Also apparently someone else quit during the episode and it was so glossed over that I didn't even notice? wild), but based on this list and what little knowledge I have of the format, I've determined that The Challenge must be the most exclusive, members-only pyramid scheme in America

Cast some new people for once! Do that challenge, The Challenge!
