"I would know", he added with a wink.
"That is a comic book I drew when I was about 9 years old, 10 years old", Kimmel explained to Abrams, who had brought the original copy with him.
The entire team confronts Damon's Mr. Bolt in a hilarious stand-off, as he releases one of his greatest weapons, The Bleachmaster, a box of bleach played by Wanda Sykes.
Affleck starred in the trailer as Muscle Man. Despite in character, Damon couldn't help but take a jab at Kimmel, to once again continue their faux-feud.
Later in the episode, Kimmel had an all-star lineup of celebrities read mean tweets about him, a twist on the usual "Mean Tweets" format. "'But that ugly bozo is still a god.' Jimmy, you don't have hepatitis". Now you're just a hairy potato. "So you're extra gross".
Kimmel and West had engaged in a Twitter fight after the late-night host mocked a rambling interview West gave to the BBC.
Kim read out an old tweet from her husband Kanye West, who went on a Twitter rant at Jimmy in 2013 after he made a spoof about one of the rapper's weird interviews. "Oh no that means you would have gotten too much good p***y in your life", wrote West in all-caps.
In a reverse move, Kimmel's favorite stars read awful tweets about the late night host. "Neither is David Letterman".
The twist on the segment was their way of celebrating Kimmel's 50th birthday.
"Jimmy Kimmel. Man, mensch, meatball enthusiast". He then showed a short gag film about Jimmy's life, hosted and narrated by George Clooney.
