One of the clips presented in this episode featured Duckman saying, "Fluffy! Uranus! My two favorite... whatever you are's." This clip was actually from an episode that, at the time, hadn't yet debuted: Season 3's "Forbidden Fruit".
The caricatures that Duckman morphs into in the climax are, in order: Ralph Kramden from The Honeymooners, Neil Armstrong, Captain James T. Kirk from Star Trek, Rod Serling from The Twilight Zone, Ed Sullivan, Mork from Mork and Mondy, The Fonz from Happy Days, Sgt. Bilko from The Phil Silvers Show, Homer Simpson, Gomer Pyle, Walter Denton from Our Miss Brooks, Dennis the Menace, Mary Richards from The Mary Tyler Moore Show, a boy from the Lassie series, Cliff Clavin from Cheers, Jerry Seinfeld, Kingfish from Amos and Andy, and Alfred Hitchcock. From the back, we also get glimpses of The Flying Nun, Bullwinkle, a Conehead, Spock from Star Trek, and Gumby.
