The evening progressed and it became apparent that not even the guests seemed to be enjoying themselves. This is exactly They claimed they were neither. Fallon received Matt Damon—with whom Kimmel has a lighthearted, long-standing feud—to the show, Justin TimberlakeIt appeared dressed in Boston Red Sox merchandise. But, at the very least there was one constant: Red Hot Chili Peppers performed on both programs.  

Having fun with the host, 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!”  

Because they were not the only late-night hosts to pull through, it seems. 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.

It was a success! Jimmy Kimmel Live tweeted“Merry #AprilFools Days to everyone and a great night!” [heart emoji].”
