Turns out, the most watched episode ever of “JKL” happened in March of 2009, when “The Bachelor’s” Jason Mesnick was his guest — right after having dumped the chick he’d picked as the winner on live TV earlier that night, deciding instead he’d rather have the runner-up chick. Nearly 3.2 million people watched the ABC late night show that night to see what Mesnick would have to say — or maybe what Kimmel would have to say to Mesnick.

 An addition four episodes, of the seven that have scored more viewers than Thursday’s episode, were nights in which Kimmel’s guest was whoever had just been named winner of  “Dancing with the Stars.”

 Comedy Central stars Colbert and Stewart stopped by Kimmel’s show on his third day broadcasting from Brooklyn; they delivered Kimmel his biggest overall audience in nearly a year.
