Rickles sat down on The Tonight Show and immediately went to work tearing Jimmy to shreds. "We've known each other a long time," Rickles said to Jimmy, "I know you as one of the finest impressionists. You do great impressions. Besides that, I'm delighted that you have a show because you're fresh, you're funny, you're great, and I want you to know something from my heart: I never liked you."
Rickles also took some jabs at The Roots, and praised the host's "great bit" of having a bandaged hand.
But give Jimmy props: He took it all with endless laughs.
