The only acceptable forms of pie come from the "I wish I were a cake" line of pies.
Chocolate creme and the like. Oreo/Reese's/etc. That kind of stuff (though key lime can be tolerable). Otherwise, throw the pie in the garbage; and take that ing imposter-cake "carrot cake" with you.
Pie is delicious. I cannot pick a favorite although pecan is near the top of the list followed closely by banana cream, blueberry, strawberry, key lime, and pumpkin.
