Apparently if you order from Pizza Hut, you get an offer for online Sports Gambling. It only makes sense, you've already proven you're a gambler by ordering from Pizza Hut.
It could be worse, when you order from Dominos, they offer to play Russian Roulette with you.
Not enough? Order from Papa John's and the delivery guy just stabs you.
@chaos440 What's weird to me is that every pizza place other than Domino's seems to have learned that nobody likes battery-acid flavored sauce.
