Pizza Plane

Considering all the bad stories we've had in the last fortnight about airline passengers stranded on the tarmac, here's a good one -- if it's true. A Continental flight crew supposedly ordered 10 pizzas and had them delivered to a jet that sat on the ground for almost 4 hours. They asked the passengers not to tell Continental, or their jobs would be endangered. The question is, how did they get the pizzas past TSA?
