Jimmy Kimmel had the misfortune of being seated next to longtime "frenemy" Matt Damon at the World Series over the weekend, and the late-night host is not letting it go. While hosting Jimmy Kimmel Live on Monday, Jimmy continued ragging on Matt, calling him "an obnoxious jerk" and comparing him to a "rodent" for eating "people's unfinished food off the floor." He also called out Ben Affleck for being a "big loser" and sitting in between Matt and Jimmy who wore "I'm With Stupid" shirts. Of course, Jimmy was only kidding. Even though Jimmy and Matt love playing up their fake beef (which we love), they are actually good friends in real life.
