Bill Murray has never been one for normalcy, especially when visiting David Letterman. Over the years, he’s donned a tuxedo, football gear, and whatever this was. But last night he made his most fabulous appearance yet, entering in a snazzy car with a fluffy dog and full Liberace get-up.

Murray was there to celebrate Letterman’s 20th year of being on CBS, and after digging up a time capsule from below the stage, he graced the nation with a short-but-sweet rendition of a timeless classic, dedicated to an old friend.
