I commuted to work on my bike, and when I went out to the bike in the afternoon before riding home I found the rear tire flat. After replacing the tube, I was in a hurry to get home so I decided to waste a CO2 cartridge instead of using my frame pump. I shot the CO2 in, and when I was putting my gear back into my saddle bag - BANG! the rear tube exploded, shoving the tire off the rim and shredding the tube. Good God it was LOUD - my ears were ringing for about 1/2 an hour afterwards. Startled the heck out of me, too.

And it was a good thing I pack two spare tubes on my commuter....

Edit: No, I do not use latex tubes on my commuter.
