Pizza Hut pan pizzas

Does anyone eat Pizza Hut regularly? I can't remember the last time I actually at a Pizza Hut pizza. When we were in Hong Kong, we saw a Pizza Hut delivery scooter and we were talking about the whole Pizza Hut thing. Then I remembered the reading program where we read books & then earned little individual pizzas. I think that was really the only time I've really eaten at Pizza Hut. There was a recent article saying how the Book It program is still going, but now under fire because of the whole childhood obesity thing. I can't remember if this was the same thing as the little green worm - where each book was another little round body part that you added to your worm. Does anyone one else remember this? Was the worm thing something else.
