A song where they sing "Hey, must be the money" or something like that. I always heard "Hey, fuck you, buddy!"
First thing I could come up with in a TF forum is a mishearing of the G1 Sunbow intro music. For nearly 20 years I thought it was 'robots in the skies' not 'robots in disguise'. Excuses: I was six and never bothered to check until I was curious where 'Robots in Disguise' come from.
