The Electric Company (1971–1977)
Narrator of 'The Adventures of Letterman': Faster than a rolling "O"! Stronger than silent "E"! Able to leap capital "T" in a single bound! It's a word, it's a plan, it's Letterman!
Blond-Haired Cartoon Man: Stupid! Listen, stupid. I'm standing here, and I feel... stupid!
J. Arthur Crank: Who's the dummy writing this show?
Mel Mounds, the DJ: Righteous, delighteous, and out-of-sighteous!
The Wall: [referring to Spider-Man] He's so dumb he's trying to eat a hot dog with no mouth.
