As the evening continued, it seemed that even the guests weren’t exactly who they claimed to be either. When Fallon welcomed Matt Damon—with whom Kimmel has a lighthearted, long-standing feud—to the show, Justin Timberlake appeared dressed in Boston Red Sox merchandise. However, there was at least one constant: the Red Hot Chili Peppers performed on both programs.
Poking fun at the host change, Jimmy Kimmel Live! tweeted a photoshopped image of Fallon and Kimmel pointing at one another, evoking the infamous Spider-Man meme, and wrote, “Someone opened the late-night multiverse!”
It appears they weren’t the only late-night hosts who got pulled through, because Late Show icon David Letterman also recorded a short audio message asking Kimmel and Fallon to stop calling him in a secondary sketch on the night.
After successfully wrapping the show, Jimmy Kimmel Live! tweeted, “Merry #AprilFools Day to all and to all a good night! [heart emoji].”
