This is actually a legit question in areas (like mine) that lose power a lot or for significant periods during the winter months.
If you KNOW bad weather (wind or ice storms) that could knock out power are coming, turn up the fridge and freezer to their highest settings.
Second, WHY THE HELL HAVEN'T YOU CHECKED THE BREAKER PANEL, YOU DUMB TWIT?
Finally, if the power does go out, the stuff in the fridge will start to spoil in as little as 6-8 hours, but the freezer, particularly if full and cold (and if you don't open it) will keep stuff for as long as 48 hours. By that point, you can either have 1--reset the breaker, 2--paid the power bill, 3--hooked up the generator, 4--shot yourself.
