One of the glass tops on my vette blew up one night.
Car always sat inside if not being driven. It was intact when I went to bed. In a gazzilion pieces the next day. To this day, I have no idea what happened.
Probably Leprechauns.
I was going to say pitbulls.
On the other side of the coin I once dropped a half full stubbie (small glass beer bottle) onto a concrete floor base first, and it didn't break, and didn't spill the beer either. Someone was looking over me to get my alcohol intake that day...
