There is a scene in Dazed and Confused that always gets me. It's when they are having the party at the moontower. Slater and his buddies and Mila J. are sitting on a car talking about George Washington growing pot.
If you watch what is going on in the background behind them, a guy walks up to a car, bends over and passes out. Then some other folks walk up to him, look down at him, and then just keep on walking! Makes me laugh every time.
There is a lot going on in that movie if you bypass the main scenes and just watch the background stuff. One of the greatest films ever!!!
