iPod Shuffles Indestructible?

I have an iPod Shuffle (2G) that I've been using for my 430am trips to the gym for over a year now. I have managed to leave it in my shorts and washed / dried it no less than half a dozen times. Every time it comes out dead, but if I give it a day to dry out it will re-sync and keep on playing just fine. You just can't kill these things!
