HATES QUITTING; DON'T QUIT: TJ Lavin, a professional BMX rider and host of MTV's Real World/Road Rules Challenge, is one of the few reality-TV hosts perfectly matched with his show. His laconic delivery counterbalances the contestants' overheated antics, he draws out better performances by encouraging effort and savaging quitters, and he openly disdains his charges. According to a story he told on Bill Simmons's podcast, he waited out a rage tantrum by perennial psychopath CT; he presided over the funniest spelling bee ever televised; he rationed his catch-phrase, "you killed it," because he knew that Simmons and his friends were using it as a metric in their RW/RR Challenge pool.
Lavin took a bad spill at a BMX tour event and is in a medically-induced coma. Hopefully he'll be better soon to calmly belittle more immature Challengers.
