One of my friends used to tell the story of the exploding hedgehog.

It was an epoxy encased hedgehog that sat on a mantleshelf. Unbeknownst the owners it was slowly rotting and the gas pressure was building inside the block of resin. Eventually the pressure got too much and the resin block exploded, covering the room in bits of hedgehog and resin.

Have you heard of the epoxy hot dog?
