Kevin Spacey has a pretty impressive reputation as an impersonator. The man has the ability to take on the mannerisms, posture, and tone of voice of just about any celebrity. So, while making an appearance on the Late Show with David Letterman, Letterman couldn’t help but suggest Spacey do a few impressions near the end of the show. (Give the people what they want!)

Spacey hunched over and delivered a spot-on imitation of his longtime mentor, two-time Oscar winner Jack Lemmon. The actor went to discuss his relationship with Lemmon, a man he’d known since he was 13. Letterman then requested another famous talk show host, Johnny Carson.
