Very funny concept, and alright execution. I vehemently disagree with the pineapple thing. If it's their pizza, why does it matter? There was no evidence that the pizza was to be shared. The same goes for the steak. I don't think it's a crime to ruin your own meal.
Am I just dumb, or does "Fingerprints on the last square match the defendant. The square itself is missing." not make any sense?
