Pi Day
Here's the one I made. I cheated by using store bought crust, but it came out looking pretty good.
I'm tempted to have pizza for lunch, in honor of comedian Brian Regan. He does a joke about the day he started college, when his new room-mate from New Jersey asked him if he wanted to split "a pie". Having never heard someone refer to a pizza that way, he was a little puzzled, but since he was hungry he said sure. That's how they ended up having half pepperoni, half pumpkin.
