I didn't have one explode, but I had one or two that were severely infected and highly overcarbonated. I did have a Sixpoint Rad can explode in my closet, funny enough...
My local beer store guy told me he's had them explode in the back of his store. I picked up their Dunkelweizen and couldn't finish it because it was so over carbonated.
I bought a six pack of their English IPA and it was in my car for an hour in the heat when my wife and I stopped to eat and all the bottoms of the cans had bulged out and the felt like they were about to explode. Never seen anything like it before.
