Many years back an Oregon town tried to get rid of a huge dead stinking bloated beached whale by blowing it up. Which only resulted in huge chunks of whale being dispersed widely around, not exactly the result they wanted. This was not an urban legend; the newsreel-like video is widely downloaded on the net.

It's not the same thing, but what you see there are the remains of a 10-meter-long whale after they used an explosive charge to kill it, after it beached itself in South Africa. The local folks found that they could not save it and decided to give it a humane death. They are hopeful that the tides will carry the carcass out to sea.
