Matt Damon may have lost the Best Actor Oscar this year to Leonardo DiCaprio, but he did succeed in appearing on Jimmy Kimmel Live! which has “banned” him for quite some time.

Fans of the ABC late-night talk show know that Damon and Kimmel have had a longstanding “feud” that began when Damon got a little too close to Kimmel’s former girlfriend, Sarah Silverman. Since then, the The Martian actor had been permanently forbidden to appear on the show, but that hasn’t stopped him from trying to get in.

Thanks to his best friend, Ben Affleck, who was scheduled to appear on Kimmel’s post-Oscars special last Sunday, Matt Damon was able to sneak in to the set, albeit indiscreetly. Affleck walked onto the stage wearing an oversized black winter coat and looking unusually bulky, to which Kimmel said, “I hate to say it, but you’ve ballooned.”

Despite Affleck’s protests, Kimmel started unbuttoning the coat and revealed a hidden Matt Damon curled up like a baby, looking quite sweaty and a little red-faced. The audience screamed in delight, but Jimmy Kimmel was having none of it.

While Affleck tried to reason with Kimmel, Matt Damon proceeded to sit on the guest coach and soaked in the adulation of the crowd. His appearance was short-lived, however, as Guillermo quickly wheeled him off the stage.

The faux feud between Kimmel and Damon have included some of the most entertaining pranks in recent TV history. Kimmel has constantly bumped Damon from the show and often ends an episode with the line: “Our apologies, Matt Damon; we ran out of time.”

Matt Damon Takes Over ‘Jimmy Kimmel Live!’

In 2012, Kimmel cut out Damon’s scenes from an Oscars parody film he made called “Movie: The Movie,” causing the actor to furiously storm out of the studio. But Damon got back at Kimmel through the comedian’s then-girlfriend, Sarah Silverman – together they made a music video entitled, “I’m F—ing Matt Damon.” Finally, Matt Damon ambushed Jimmy Kimmel’s show in 2013 during which he gagged Kimmel and kept him bound to an office chair for almost the entire episode.
