The episode "The Groovesicle", which has Robot Jones and his friend Socks watch a music video of a band called The Lavender Fudge Experience singing a song called "The Nudist and Mr. Pendleton", with the nudist being a jovial man in a bowler hat with an umbrella and Mr. Pendleton being a dog trying to cover up the nudist's nudity.
Robot Jones thinks over Gramps Unit's claims that humans and robots do not mix and ponders whether his beliefs are true. Some dust and bolts then burst out of Gramps Unit, which causes Robot to remark "Or maybe he's just a rusty old bucket of bolts".
Cubey worries about what he'll be called if he fails to solve Robot's jumbled up face. He imagines Mitch calling him "Gooby", another kid calling him "Ooby", and Shannon calling him "Stupid idiot loser".
