Clooney, 56, hosted a birthday retrospective on the late-night talk show host. “Hello, I’m George Clooney. Join us now or the next four and a half hours, as we take a look behind the beard: ’50, Fierce and Fabulous’,” said the star.

The actor made reference to Kimmel’s 1999 Comedy Central show, “The Man Show”.

“This level of high-minded satire would not go unnoticed by the heads of American Broadcast Company,” Clooney teased.

Clooney also joked about Kimmel’s life-long, “boundless and borderline psychotic” obsession with David Letterman.
