Shake base:

2 1/2 cups vanilla ice cream 1/2 cup milk
3 tablespoons graham cracker crumbs whipped cream

Banana cream pie:
add 1 ripe banana

Coconut cream pie:
add 1/4 cup cream of coconut

Chocolate cream pie
add 2 tablespoons chocolate syrup

Strawberry pie
add 1/4 cup frozen sweetened sliced strawberries, thawed

Mix all ingredients (reserving one of the tablespoons of graham cracker crumbs) in a blender until smooth. You may have to stop the blender and stir the shake with a spoon so that it blends evenly. Pour the shakes into two 12-ounce glasses. Garnish each serving with a dollop of whipped cream, and shake the remaining tablespoon of graham cracker crumbs over the top.
