The episode: “Project Moonbase,” ep. 109
The riff: A running dialog between Joel and Crow as a rocket prepares to blast off into space.
The explanation: This appears to be a reference to the characters of Bob and Doug McKenzie, the Canadian brothers and hosts of “Great White North” on Canada’s Second City Television, aka. SCTV. The SNL-like sketch show would feature Bob and Doug (played by Rick Moranis and Dave Thomas) as inept public access TV hosts who would mostly just argue with one another, call each other “hoser,” and tell each other to “take off,” which is probably where they got the inspiration for this riff. Although initially created to spite the network’s request for “Canadian content,” the characters became very popular, even getting their own spin-off movie, “Strange Brew.”
Novelty factor: I’ve never actually seen “Strange Brew,” but I’ve been introduced to a number of SCTV sketches over the years and could generally recognize that this was a McKenzie Brothers reference.
