David Letterman will bid adieu to late night TV on Wednesday, May 20th, when he hangs up his hat on CBS’s Late Show. He will host his final guest the night before–May 19th–and it is the same person he hosted as his first guest 33 years ago.

Bill Murray was David Letterman’s first guest and will soon be his last. He has appeared on Light Night and The Late Show 43 times in 33 years.

During his first visit with David Letterman, Bill Murray said, “You got out of Indianapolis and didn’t look back. I’m just waiting for the other shoe to fall on you, man, and I want to be there when it hits the floor! I had a chance to strangle Richard Nixon and I didn’t—and I regret it!”

Check out the first time Bill Murray was a guest on David Letterman’s show.

Tom Hanks and singer Eddie Vedder will appear on The Late Show to wish David Letterman well on Monday.

This Sunday, David Letterman will chat with Jane Pauley on CBS Sunday Morning. It is his only scheduled TV interview before hosting The Late Show for the final time.

Are you finding it hard to believe that David Letterman is leaving late night TV next week? Despite the fabulous guests the talk show host will chat with, the coming days will be bittersweet for fans.

Will you be checking out David Letterman as he chats with Tom Hanks on Monday, Bill Murray on Tuesday, and appears on his final show on Wednesday?

CBS says the final show “will be an hour filled with surprises [and] memorable highlights.”

David Letterman has made lots of memories over the past 33 years–for himself, his guests, and for his fans.

Thanks for those memories, Dave.
