Something a little, well, different.

If you think about it, you've probably eaten no more than a dozen pies in your life. Seriously, after the big names that everyone knows, the pickings get a little slim. You've most likely eaten:

Apple

Pumpkin

LMP

Pecan

Banana Cream

Coconut Cream

Chocolate Cream

Peanut Butter

Berry (a catch all covering all summer berry pies)

Peach

And, um, yeah...that's probably about it. Sure, anyone who reads this list will be able to think of a couple more, but the common variations get narrow really fast. 

I remember complaining, as a kid, about a culinary experiment my mother put in front of me: "Why can't you just make the food that you know we like?" (As an adult, I'm already annoyed with my nine-year-old self. "Just eat it, kid, you might like it." But that's beside the point.)
