Cheap and easy way to heat pizza (as long as the cheese and grease don't drip into the toaster).

Looks like Hiroshima in your oven.  I see a mushroom cloud in there.

Not only is it not secure but I would think the smell alone would attract critters into your home.

Yet another reason to order Pizza at work, you can recycle the box into a hat!  

I'm not sure what worse reheating your pizza on an iron or on top of the toaster (seen HERE)

Hummm I must admit I haven't tried this (yet) but this might not be a bad idea to re-heat pizza.  So WIN or FAIL?
