Before the Montage
The film's main character, Thornton Melon (Rodney Dangerfield) has been paying people to do his homework and take his tests all year, but with an oral exam coming up, he has to learn a semester's worth of information in just one night:
And even though that last sentence describes the finals experience of pretty much every college student we've ever met, Rodney Dangerfield is old so, you know, it's worth making a movie about.
Cue the Music
Instrumental hoo-ha. We think it's piano.
The first rule of the training montage is that you must practice the skill you are trying to learn in a variety of beautiful or quirky locations. Whenever Rocky needed to prepare, he'd just train in a bunch of different scenic places all over the city of Philadelphia, or do something quirky like punch raw meat. Dangerfield apparently saw those films, because he studies in some of the zaniest locations ever: while getting a massage, while taking a shower and even at night in the dark, apparently before flashlights were invented:
Not only does he pass, but he is able to win his school's diving competition too, which means that the film gives us the pleasure of seeing a geriatric Rodney Dangerfield in both the shower and in a bathing suit.
