In "No Meals on Wheels", Peter Griffin says the situation with paraplegics at Big Pete's House of Munch is weirder than M.C. Escher's attempts to become a rapper. The setting of the video for "Going Up the Stairs" was based on Escher’s Relativity. Stewie has the same picture in his and Brian's dorm room in "Brian Goes Back to College". Stewie is fond of calling it "Crazy Stairs".
