“Jay was always the funniest. Without question,” Letterman said on Marc Maron's WTF podcast. “In Jay’s case, it was not so much joke writing as it was… his attitude was hilarious,” he added. “So whether he had a joke or not, it was funny. And people loved him.” But Letterman says their rivalry was the result of Leno's insecurity. “I’ve always said two things: He’s the funniest person I was ever around; and what we see is a manifestation of deep insecurity," said Letterman. "But as a standup, was there anybody (as good?)” Asked if he would ever see himself reuniting with Leno for a future project, Letterman responded: “No, not really."
