What is your all-time favorite 'popcorn movie'?

Ahhhh, summer. The long lines at the box office for the midnight release of the 3rd sequel in your favorite trilogy. The $18 tickets for the 3-D, IMAX presentation of the 2-hour movie. And the smell of hot buttered popcorn. I remember being a kid and everyone complaining when the first release of Return of the Jedi tickets jumped from $3.50 to $4.25. God forbid!! Now you can pay 3 times that for a soft drink with an undertow. But I digress. What is your all-time favorite 'poocorn movie'?
