I once invented a brilliant game - I'd sit at the top of the stairs and throw cat biscuits to the bottom. My cat would eat them, then I'd shake the box, and he would run up the stairs for more biscuits. Then - of course - I'd throw a biscuit back down to the bottom. I kept this going for about half an hour, amused at my little game, and all was fine until the cat vomited. I felt absolutely dreadful.
Have you accidentally been cruel to an animal?
This question has been revived from way, way, way back on the b3ta messageboard when it was all fields round here.

Actually, that's not true. While it would undoubtedly have suffered a horrible death, microwaves heat from the outside in like any other electromagnetic radiation absorption process. The difference is that because the wavelength of microwaves is far longer than infrared radiation (like you would get from a grill for instance), the fall off in absorption is much slower, so the inside gets almost as much radiation as the outside.
With infrared, the vast majority of the radiation is absorbed in the outer layers of the food, falling off exponentially as it penetrates further. So the outer layers burn, while the inside relies mostly on conduction to transfer heat form the outside and cook the bulk of the food.
