Saw this for my birthday with some friends and I think just about everyone enjoyed it. Alot of the theatre was laughing, especially during the "dicks" part and the police officer scenes. I found Seth a bit annoying, though, and yeah, I agree he cursed a bit too much. I don't know anyone IRL who curses THAT much actually.

Anyhow, moving aside from that - my favourite characters would have to be Seth Rogen and Bill Hades as Officers Slater and Michaels. They were huge assholes but their chemistry was awesome, especially with the dude who played McLovin (couldn't remember his real name). Speaking of McLovin, I think he did a pretty good job also (also for some reason, he reminded me of Psyburn).

So, yeah, it's pretty much difficult to find a vulgar comedy that is hilarious nowadays. I'd say this is definitely a movie that knows its crowd.
