The only reason I noticed this is because I saw the DVD commentary. So before everyone starts writing "Kevin Smith explains that in the commentary," I know. This is for the unfortunate people who haven't seen the DVD yet.

When Holden is talking to Jay and Silent Bob, Bob begins to tell his story. Jay acts surprised that he was never told about the girl Amy in Bob's story asking, "What, did she live in Canada or something? Why don't I remember that?" But, and the end of the story Jay asks Bob, "Why do you always have to tell that gay story?" Either Jason Mewes was really really stoned or it's just a slip up. Those of you who don't own the DVD, check it out and you decide.
