(I was thinking of the exact same stupid joke) Strawberry Rhubarb (ok, I'm sure I butchered that spelling).
I don't have sepcific pie as a favorite, but my top 5 are: Lemon meringue Chocolate Cream Pecan Apple (Hot) Blueberry (Hot) I'm obviously missing out on the Key Lime pie. I can honestly say I can't remember ever having a slice in my 29 years. I'm going to have to go out and find one.
I'm a big Key Lime fan but the single greatest pie I've ever had was the pecan pie at Commander's Palace in New Orleans.
My mom's rhubarb pie, or my apple pie with a crumb topping.......it is a tossup and I am biased toward the apple too... Damn these tasty treats!
This should be a top 10 List: 1 - Fresh Strawberry 2 - Strawberry-rhubarb 3 - Key Lime 4 - Banana Creme 5 - French silk 6 - Blueberry (my wife's - not too sweet) 7 - Gooseberry 8 - Apple 9 - Peach 10 - Coconut creme
shoo-fly pie is good, too I worked in an IBM plant in PA one summer and their vending machines had slices of it, made locally by (it claimed) an Amish community.
