Strange Brew (1983) This is possibly the best movie ever with beer and drunks. Any scene in this movie could be considered a classic.
Doug McKenzie: Yeah. OK, well, uh, we found, uh, this mouse in a bottle of YOUR BEER, eh. Like, we was at a party and, uh, a friend of ours - a COP - had some, and HE PUKED. And he said, uh, come here and get free beer or, uh, he'll press charges.
There were some notable mentions. They are either TV only, movies that many haven't seen, or just a bit too old to remember.
