On Sunday night, during the 68th annual Primetime Emmy Awards, Matt Damon continued his long-running feud with late night host and host of the Emmys, Jimmy Kimmel. 

Following “Jimmy Kimmel Live!’s” loss to “Last Week Tonight With John Oliver,” Damon came on stage to throw salt in Kimmel’s wounds. “This is so humiliating,” Damon told Kimmel. “I’m sorry. I mean, you lost, and now you’ve gotta stand out here for the rest of the night when you probably just want to go home and curl up and cry.”

While eating an apple, Damon continued with the jokes, asking the crowd to cheer Kimmel up. “Can we cheer Jimmy up? He’s a big loser — a big round of applause. You’re a pretty big loser, I for one am really sorry about that.” Damon then left the stage but not before delivering his final blow: “Tell your mom, I like them apples.”

If you’re wondering why Damon and Kimmel would have a feud, it all dates back to the third season of Kimmel’s show. During a less than stellar episode, Kimmel ended the show by apologizing to Damon for bumping him from the episode. After the joke got laughs, Kimmel continued to make the joke every night.

“We had a bad show … The guests were bad, and I was feeling pretty bad about myself at the end of the program,” Kimmel told NPR in 2013. “And I decided to say, for the amusement of one of our producers who was standing next to me … ‘I want to apologize to Matt Damon. We ran out of time.’ And he got a kick out of it, the producer, so I just started doing it every night to amuse him.”

Kimmel revealed he had no particular reason for picking Damon’s name, saying it just “popped into” his head. “I was trying to think of an A-list star, and somebody we absolutely would not bump if he was on the show.” As Kimmel continued to use the joke for a year, Damon was eventually invited to appear on an episode but Kimmel had to apologize to Damon for once again running out of time. This led to a staged fight between Kimmel and Damon that featured Damon storming off the set.

The fake feud has continued throughout the years with Damon making multiple appearances on the show, including going to couples therapy with Kimmel and even taking him hostage and hosting the show himself. Before Sunday night’s incident, the most recent interaction between the two came during an August episode of “Jimmy Kimmel Live!” when Damon made an attack ad against Kimmel.
