What's the name of that song Recently shown on Adult Swim showing the cast of ATHF singing a jazzy tune?

The song shows the cast of Aqua Teen Hunger Force (ATHF) scat singing
(I believe) in a jazzy tune. In the middle of the song, Meatwad
spontaneously bursts into flames, startling Master Shake and Frylock,
causing them to back up but continue singing.

I've heard that song several times on Adult Swim, but I don't know
what song it is or where I can find out what song it is. Can someone
help me out?
