Last night was Jay Leno's final night of hosting The Tonight Show... and that's all that needs to be said about that. HOWEVER! Over on ABC, Jimmy Kimmel has been doing what he does best—hilariously humiliating the CRAP out of Matt Damon. The pair have been jokingly going at it for years, but Damon's appearance last night on Kimmel's show was especially funny. Here he is with the cast of The Monuments Men—who, perhaps too happily—join in on the joke.

If you'd like more, here's Kimmel finally asking Damon a "real question"—and of course, things go terribly wrong from there.

Aaaaand... oh, screw it. Here's another terrific installment of Kimmel's "Mean Tweets," featuring Clooney, Benedict Cumberbatch, Damon, Jon Hamm, and Jennifer Garner... who apparently looks like a "duck's vagina"?
