You're trying to be smart but no one is stupid enough to buy 2 Papa John's Pizzas for 1 BTCitcoin. I would recommend you to try your luck somewhere else because on this forum users aren't naive enough to purchase 2 pizzas for a Bitcoin because with a single Bitcoin we can buy so many of those pizzas.
People have different reasons to get things, you would be surprised how much people paid for some items that aren't even Worth it in the first place.
Regardless I believe this was just a joke and for fun but if this post was to go main stream and may get high publicity many people would definitely take the offer and would want to be part of the recreation of the legendary Bitcoin pizza .
