Learned from: Sex Drive (2008)
Complex says: Persistence is admirable, but foolish repetition? It doesn’t get much worse than that. For example, check out the slept-on comedy Sex Drive’s Andy and Randy, two young Jeff Spiccoli-wannabes devoid of any shame or discernable game. Their sophomoric and foul pickup lines assault women with a machine gun’s verve, pushing them into a tier of failed daters that no guy wants to enter: Losers that man want to snuff in the face just as much as the women they’re annoying.
