Preheat oven to 350°F (177°C).
Prepare graham cracker crumbs by one of two methods:
1. Coarsely break crackers and place in the food processor. Process with metal blade until finely pulverized.
2. Place crackers in a plastic bag and crush them with a rolling pin.
Add melted butter and combine. This will require a few pulses in the food processor or a few seconds mixing by hand in a bowl.
Press the crumb dough into a 9-inch(23cm) diameter pie pan, spreading them evenly over the bottom and sides.
Bake for about 8-10 minutes at 350°F (175°C).
