a strange song.. hippies buying a meat shake?

I saw this song on a video clip show, it was weird but pretty cool! It was spoken, it was these hippy type people at a drive-thru, and the guy at the window was trying to sell them a meat milkshake, and then suggested they go across the road to some vegetarian food place... it was a cartoon, and the guy at the window almost sounded like Austin Powers?
if anyone knows the name of the song, id be most grateful
