Hey Frank,
I know its a little off topic but Heidi's hard pizza comment reminded me of a funny story.
A while back me and a bunch of friends were making some oven pizza's, when we took the pizza out after the correct time and were trying to cut slices we realized that it was way too hard. Turns out we had left the cardboard on the bottom of the pizza and it had baked into the crust.
Love the show!
