Kimmel and Damon became friends after Kimmel pretended to have a feud with the actor as a joke for Jimmy Kimmel Live! in 2005. The fake feud started when Kimmel jokingly said, “Apologies to Matt Damon, but we ran out of time,” during a season 3 episode of the show, despite the fact that the actor was not slated as a guest.

We have got to get him to the hospital,’ because if he dies in my house, I’m going to prison for the rest of my life.”

The epic story of Jimmy Kimmel and Matt Damon is well known by now. What started as a running gag that saw Damon repeatedly “bumped” from Jimmy Kimmel Live turned into a sort of faux feud, sort of on par with the ongoing battle between Hugh Jackman and Ryan Reynolds.
