RegularGuy may be on to something.
When something is dead and left to decay, they will usually swell to an abnormal size. The yucky consequence is that if the dead body is moved and something happens, like someone drops it, it will explode. Gross, but true. So next time you see a dead beaver on the side of a road and it's larger than normal, try not to hit it... you could end up with beaver matter all over yourself!
On a slightly different note, I read a story in the Chicago Reader about a company that cleaned up homicides and suicides. They detailed a gross situation where a fat man died, and he had rotted in his apartment for several days before being found. His body had swelled, and it was also hot because it was summer. He was so fat that the paramedics dropped him, and his body remains exploded all the way down the hallway of the apartment complex, and they said it took them a long time to clean that mess up.
Yuck.
