Has David Letterman EVER had this much fun before?
The "Late Night" host had "Billy on the Street" star Billy Eichner on his show Thursday night, where he had the 67-year-old in stitches playing a game called "Celebrity Child or Kentucky Derby Winner?"
The game's rules were simple: Billy read out an outrageous name like Moxie Crimefighter and Dave had to guess whether it was a star's offspring or a prize-winning horse.
But with some of the absurd things some people are naming their kids these days, it wasn't easy for Letterman.
Between Dave's giggles and the all-out screaming match that ended the segment, this was one interview that was as much fun for Letterman as it was to watch at home.
Eichner also had a very memorable moment during the Emmys last month -- stealing the show from host Seth Meyers with an absolutely hilarious game of "For a Dollar."
We LOVE him.
