In an episode o' t' animated TV series South Park" entitled "AWESOM-O," Cartman disguises himself as a robot t' learn Butters's secrets.

Butters believes t' robot is his new best friend and sings a shanty obviously inspired by Peglegged Wobbling Harry Nilsson's "Best Friend":

 

Hey there, arrr, have you heard about me robot friend?
He's metal and small and doesn't judge me at all.
He's a cyber-wired bundle o' joy ....
