Jon Stewart breakdances onto Jimmy Kimmel Live with an incredibly awkward offer

Jon Stewart ignites Jimmy Kimmel, Matt Damon feud for charity

Night of Too Many Stars airs Sunday, Nov. 18 on HBO with the goal of raising funds for people with autism. “All the late-night shows are gonna be involved with great auctions and it’s gonna be incredible,” Stewart said. Louis C.K., Stephen Colbert, Abbi Jacobson, Jordan Klepper, Hasan Minhaj, John Mulaney, Olivia Munn, John Oliver, and Adam Sandler are among those who’ll appear on Night of Too Many Stars.

“The reason I’m here with that,” Kimmel said, pointing to Damon, “is to raise money for NEXT for AUTISM, an organization that works to improve the lives of people living with Autism Spectrum Disorder. He’s here for the publicity.”

“That’s bulls—t,” Damon shot back.

“You’re bulls—t,” Kimmel replied.

And it got worse from there.

Kimmel and Damon have been in a years-long fake feud for the enjoyment of viewers ever since the late-night personality joked about bumping The Martian star from Jimmy Kimmel Live. Most recently, Damon crashed Kimmel’s interview with Thor: Ragnarok‘s Chris Hemsworth to reclaim some screen time.
