I would sacrifice my first born to the devil. Of course, I'm going to do that any way, but sounds like Satan just sweetened the deal.
I would walk my happy ass down to the store, open up the little freezer thing, pick it up and take it to the counter. When the cashier waves their magic wand over it, I give them the amount of money they tell me. Yay.. I have successfully acquired a Klondike bar!
I would shove a flaming cactus up my rectum while being force-fed scorpions. Or I would just walk to the freezer, 'cause we have some.
