What makes this particular scene more powerful, is knowing that this was an obvious early criticism of Prince, what with the hard to pin down "Minnesota sound" he developed and eventually made famous.
To make matters worse for Prince, he ends up going to the Apollonia 6 show at the Taste, where the girls are dressed in lingerie and sing a ridiculously sexualized song literally called "Sex Shooter." Sample lyric: I’m a sex shooter, shooting love in your direction. Come on kiss the gun, guaranteed for fun.
(What's even crazier is that, after this film, "Sex Shooter" became a hit single, climbing to #7 on the US Dance and R&B charts, and Apollonia 6 actually went on tour to promote it. Such is Prince's power that he could make the worst song from a joke group he created for a movie become big enough to support a tour.)
