In the scene where Banky and Alyssa are sharing "oral sex injuries" tales, Banky comments that he cant move his head very far on the right. But right before, when Alyssa is kissing Kim, and he realizes he's in a gay bar, he tilts his head to the right (which is a constant Jason Lee move).

Errors in geography
When Holden and Hooper are in the record store, several albums are shown to be misplaced in the wrong sections(the Beatles in the New Age section, Green Day and Faith No More in the Reggae section, Pearl Jam and Alice in Chains in the Ska section, Sepultura in the Big Band section, Fugazi in the Jazz section, etc.)
