David Letterman has played host to a number of memorable celebrity guests over the years.
But Bill Murray sits at the apex for any long-time fan of the iconic comedian.
The actor was Letterman's first guest when Dave switched networks from NBC to CBS following Johnny Carson's retirement in 1993.
And he was booked on Tuesday, May 19 to be Letterman's last guest, considering Letterman does not plan to a formal one-on-one interview for his final show on May 20.
So, how did Murray make his grand entrance? Via enormous cake, of course,
emerging stumbling from the large dessert and giving his close friend a messy hug.
Check out the cake-based appearance via the video above and then see how Tom Hanks used a selfie stick to say goodbye to Letterman.
