Bill Murray made a grand entrance Thursday for the 20th anniversary episode of CBS's LATE SHOW WITH David Letterman. The comedian, who was the first guest on the Late Showwhen it premiered on Aug. 30, 1993, arrived in a white vintage Rolls-Royce and full Liberace regalia as he made his way into the Ed Sullivan theater. Check out the appearance below! After much fanfare, Murray took the seat next to Letterman.

Included in the show highlights was Letterman reading the Top Ten Top Ten List Entries from the Past 20 Years and performances by Lenny Kravitz and Gladys Knight.

Shared Letterman, "Here, we've done 3,901 episodes. Oh my god. And that plus our other old show, the old Late Night show, put those two together and we've done 5,711 television shows."

He later joked, "People, honestly, on a daily basis come up to me on a daily basis and say to me, LeBron, now that you've won two championships in Miami why don't you go back to Cleveland."
