The Odyssey actor and Jimmy Kimmel carried on their longtime feud after Damon tricked his way onto the late-night show stage

The Odyssey is almost here and its star Matt Damon celebrated by climbing into a Trojan horse to sneak onto the stage at Jimmy Kimmel Live.

As host Jimmy Kimmel delivered his final monologue before taking his annual summer break he was interrupted by a delivery driver bearing a giant wooden horse and a slightly small horse. Kimmel feigned surprise at the delivery, even when the driver insisted on bringing the smaller one inside the studio. “I didn’t order this horse,” he said. “I don’t know what it’s doing here. We’re doing the show right now.”

Damon then leaped out of the horse to big applause. “I don’t want the horse in here,” Kimmel told Damon. “The horse is here and there’s no take-backs, bitch,” Damon replied. “I did it!”

“I have traveled far and wide, through waves and war, to save this audience from mediocrity,” he added.

“This is trespassing,” Kimmel said. “This is another crime you’ve committed here.”

“Your face is a crime,” Damon responded. He explained that he stopped by the show to promote The Odyssey, Christopher Nolan‘s forthcoming film, which hits theaters on July 17.

“Oh my God. Did you do this movie specifically so you could sneak into this room in a Trojan horse?” Kimmel asked. “That is the saddest thing I’ve ever heard. What a loser you are.”

The appearance eventually escalated into a fight between the pair with pool noodles after Damon insulted Kimmel’s parents and Kimmel insisted this stunt did not mean Kimmel was on the show. “Everybody at home, you can wake up now,” Damon said. “Because the show is finally, finally good for like a minute.”

Damon and Kimmel have been publicly sparring since 2005. The feud began when Kimmel introduced a bit on Jimmy Kimmel Live where he feigned cutting Damon from air. “I want to apologize to Matt Damon, we ran out of time,” the late-night host joked. Since then, the pair have continued the back and forth, even involving people like Ben Affleck. 

Last year, Damon appeared on Who Wants to Be a Millionaire, which Kimmel was hosting. Damon and his game partner Ken Jennings ultimately won $1 million for Damon’s nonprofit Water.org, which helps bring clean water to communities in need. “This is the least dramatic million-dollar moment in Who Wants to Be a Millionaire history,” Kimmel said when they claimed victory.
