iPod's are too robust

An amusing story has come to light about an iPod that accidentally got flushed down a toilet. Apparently, the plumbing team hired to relieve the blockage couldn't budge it - because it was "indestructible". It had managed to wedge itself in such a way that it could simply be pushed through, so they tried breaking it into pieces. However, the fiesty little bugger couldn't be chipped, and eventually they had to resort to flushing every toilet in the building. This inevitably led to the farcical slapstick moment of having an entire floor of toilets act as geysers.
Now, why couldn't they make flak jackets or something out of iPods?
