Fallon went to Hollywood to host “Jimmy Kimmel Live!” and Kimmel flew to New York for “The Tonight Show.”
Throughout the show, they checked in from across the country.
Kimmel interviewed Hugh Jackman and Bridget Everett, while Fallon interviewed Justin Timberlake and Kimmel’s Aunt Chippy. Red Hot Chilli Peppers appeared as a musical guest on both shows.
Fallon and Kimmel said they’ve been talking about the prank since April 2020.
