David Letterman celebrated his 20th anniversary on CBS Thursday night with a familiar face: Bill Murray.

Murray, who was Letterman's first "Late Show" guest on Aug. 30 1993, made an encore visit, joking that he couldn't remember much about that time period.

The 62-year-old Murray emerged on to the stage in a vintage Rolls-Royce, channeling his best Liberace with an elaborate white get-up that included a fur-trimmed cape. To top it off, he was carrying a white toy poodle.

"Wow...Delightful. I didn't know you had a dog," Letterman pointed out. "I had to get something that went with this outfit," said Murray, who later took a jackhammer to the floor, where he found a time capsule filled with "artifacts" from 1993. Inside he discovered a newspaper with a headline about rival late-night host Jay Leno, as well as a hairpiece Murray said Letterman had "worn" on his first show.

Murray's appearance was just part of the anniversary celebration. Letterman read a special Top 10 list from the past 20 years, and Lenny Kravitz and Gladys Knight performed.

Letterman, 66, noted, "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."
