Okay Mitchell, here's what i got about pie:
Pie. Definition: A pie is a baked dish which is usually made of a pastry dough casing that covers or completely contains a filling of various sweet or savory ingredients.
Pies are defined by their crusts. A filled pie (also single-crust or bottom-crust), has pastry lining the baking dish, and the filling is placed on top of the pastry, but left open. A top-crust pie, which may also be called a cobbler, has the filling in the bottom of the dish and the filling covered with a pastry or other covering before baking. A two-crust pie has the filling completely enclosed in the pastry shell. Flaky pastry is a typical kind of pastry used for pie crusts, but many things can be used, including baking powder biscuits, mashed potatoes, and crumbs.
Pies can be a variety of sizes, ranging from bite-size to ones designed for multiple servings.

Savory pies
Sweet pies
Some of these pies are pies in name only, such as the Boston cream pie, which is a cake. Many fruit and berry pies are very similar, varying only the fruit used in filling. Fillings for sweet or fruity are often mixed, such as strawberry rhubarb pie.
Oh and by the way, my favorite pie is chocolate pie filled with ice cream and has chocolate chip shavings on top with whip cream.
