It was 2003, and Kimmel’s show wasn’t the mega-ratings driver it is today.
So, at the end of the night, Kimmel took a chance one that would change everything.
“We had a bad show.

The guests were bad, and I was feeling pretty bad about myself at the end of the program.
We ran out of time,'” Kimmel toldNPRin 2013.
Wanting to pick a celebrity they would not bump, Kimmel chose Damon.

Even Kimmel can’t believe the joke’s longevity.
At this point, the pair hadn’t even met.
“Maybe I had a movie out that week,” Damon guessed during a SiriusXM interview, perYoutube.
“It changed the course of both of our lives,” Damon said.
We’ve kept this feud going for, you know, it’s gotta be 15 years now.
We’ve had a lot of fun doing it."
As their so-called feud grew, the pair even brought their friends and partners into the fun.
