What's the movie where...
There's a scene where these two guys are dehydrated and have been walking for miles or something, and they finally find a gas station. And they go in and start wrecking the place trying to get a drink or some food. I think the one guy drinks a whole gallon of milk because he's so thirsty.
And the gas station clerk thinks he's being robbed when really the guys are just really thirsty.
Can't think of the movie. Want to say Harold and Kumar but I don't think that's right. It's a movie like that though I'm pretty certain.
