When Ben Affleck appears on your show, you better be ready for some serious surprises!
"You do the super hero movie and then muscle turns to fat," the Batman v Superman: Dawn of Justice actor explained while holding back laughs.
Kimmel inspected the suit, carefully, and asked him about why his suit was moving around as if someone was inside.
"I didn't realize that this was about body shaming tonight," Affleck retorted. And in a blink of an eye, Matt Damon popped out from under Affleck's suit.
Kimmel, who was completely shocked by Damon crashing the interview, jumped back into his seat while Affleck said, "I just think it's time to bury the hatchet here."
"This is amazing. This is wonderful," Damon joked while relishing in finally getting a chance to sit on a Kimmel hot seat. "I feel like Dorothy."
"This is potentially breaking and entering," Kimmel shouted to Affleck. "This is trespassing."
Damon was quick to chime in, though, "He's an invited guest and you should treat him better."
After a few laughs were shared, and some tense jokes, Kimmel told the Oscar-winning duo, "I know your intentions were good but I'm furious right now."
You may recall that Damon and Kimmel's faux feud began all the way back in 2003, and the two have never shied away from poking fun at one another ever since.
