When one of the characters sits in a chair with a fishing rod:
Servo: Typical male: Sittin' in a chair, playing with his rod.
Deep South: Crow sings "I'm glad I'm not in Dixie" after the Sheriff has the unfortunate habit of calling a black man "boy".
Fan Disservice: Tom and Crow have Prof. Bobo and Brain Guynote who sports purple nipples perform a scene from Glengarry Glen Ross in the nudenote though Bobo has so much fur it's impossible to tell if he's nude to prove their point that nudity makes any movie scene better. Mike then points out to the robots that they probably should've specified female nudity.
And then the 'Bots suggest Mike seeing Pearl nude.
In-Universe, this is Mike and the 'Bots reaction to seeing Dr. Leopold in his boxer shorts as he prepares the transformation process.
Mondegreen: Invoked. Early in the film, Mike and the bots mishear "sargassum" as "sarcasm".
No Theme Tune: Referenced: The movie's opening titles contain no music, prompting Crow to ask: "Uh, theme music? Anything you want to throw in at this point?"
Take Over the World: One host segment has Crow parody Leopold's opening narration, but focusing on shoes instead of fish (as Mike is trying to polish his shoes). He also wedged himself into the bulkhead.
