Parts that crack me up every time
1. Glenn getting punched in the face.
2. The store clerk not believing the brothers will come back so he gets up only to see the car coming back...so he sits back down and counts some more.
2. The money exploding in the brothers' faces.
3. The bankers telling Holly Hunter (as she's running away from the Devil essentially), "Lay down on the floor, Missy!"
JAWS - best film ever made.
