John Lithgow Nails Rudy Giuliani with Pitch-Perfect Impression

From Winston Churchill to Rudy Giuliani, John Lithgow can do it all. Last night on The Late Show with Stephen Colbert, the legendary actor brought down the house with his pitch-perfect impression of the former NYC mayor. Lithgow-as-Giuliani opened by insisting that he's never been on the show before ("Sir, you've been on three times," replied Colbert), before turning his attention to his recent Fox News ban, finding a new home on Cameo, and the Dominion lawsuit.

By the end of the "interview," Colbert had enough with Giuliani's ramblings. "Sir, stop!" said Colbert. "Even by your own standards, you're humiliating yourself on television right now."

"What?! They let me on TV again?" asked Lithgow's Giuliani. "Oh, you're right, Stephen — I look like a total embarrassment!"

The Late Show with Stephen Colbert airs weeknights at 11:35 PM ET on CBS.
