I've never really thought one way or the other about Kimmel (other than his phenomenal work on The Man Show and Win Ben Stein's Money). I always assumed he was funny seeing as that his show survives (which I guess is a testament to his writers as well). But this video sealed it for me. To go on Leno's show and continuously bitchslap him everytime Leno opened his mouth takes balls. Well done, Jimmy.
