As Bill Murray was the first-ever guest on Letterman's Late Night show, it was only fitting that he also acted as his last.
When it comes to Bill Murray, it’s always safe to expect the unexpected, so the actor didn't disappoint when he entered the studio by jumping out of an oversized cake.
Wearing overalls and goggles and covered in cream, he hugged Letterman, rubbed his messy hands in the 68-year-old's hair, fist-bumped the musical director and then ventured into the audience to lock lips with a female audience member.
Following the interview - where he downed a few shots of vodka - he then hopped over to MSNBC for The Last Word.
Though it seemed he may have celebrated a little too hard at CBS.
