Ben Affleck Sneaks 'The Martian' Matt Damon Into 'Jimmy Kimmel Live' As Oscar Awards Guest!

Right after this year's Oscars night, there was a special post awards show on Jimmy Kimmel Live, and the late-night host had two-time winner Ben Affleck on. The actor and director sneaked in his bro and Kimmel's nemesis, Matt Damon, attempting to end the two stars' ongoing feud once and for all -- but it's not easy for the Martian actor to be on Kimmel's guest chair!

In the latest episode of the ongoing fake feud between Kimmel and Damon, a common friend tried to solve things through by forcing them to talk. As a guest on the show, Affleck came in obviously carrying something underneath his suit, and as the talk show host forced him to spill, it turned out Damon had been sneaked into the studio.

A furious Kimmel told Affleck he was disappointed even though he knew he meant well, while Damon sat on the second chair of the guest area, looking smug. In the hilarious bit, the Jason Bourne actor makes himself comfortable as a guest on the late-night show while Kimmel is fuming.

In the exchange, Damon tells Kimmel to stop treating Affleck so poorly, and ultimately the comedian has him kicked out of the set.

Of course, fans Kimmel fans know Damon has been waiting to become a guest on his talk show since it began, but Kimmel never has time to have him on and he's been waiting on the green room for years. In the past, Damon has appeared for short amounts of time on the show, always to Kimmel's displeasure, who's kicked him out in every way possible and given him all kinds of nasty looks.

Throughout Jimmy Kimmel Live's history, Damon has shown up quite a few times, including hijacking the show and making a hilarious skit with Kimmel's then-girlfriend Sarah Silverman, where she addresses him in a clip entitled "I'm F***ing Matt Damon," which gave the comedienne her first Emmy.

Just in case you haven't kept up with the years of going back and forth, enjoy a supercut from the first few of the long and hilarious late-night feud!
