In 1982, Late Night with David Letterman premiered on NBC with Bill Murray as the first guest.

Ever since, Murray has been one of the most memorable guests through Letterman’s career and it was only fitting that the last guest that Dave interviewed would be Bill. 

While there was a retrospective portion of Bill’s segment, there was, of course, hijinks involving a giant cake and starting a flash mob.

If you’re thinking the comedy is going to be pretty much focused on Dave Letterman today, you’re right on the money.
