How??

This is an oven mitt.  I'm not sure how it caught on fire, nor am I sure why someone would throw it out in the driveway ON FIRE...or why would you throw it in the driveway at all...or how on Earth did you catch the thing on fire?  30 minutes later I was told about this (it was so funny to them) so I decided I'd better check on this amazing sight.  It was STILL on fire, (picture above is what I saw)  just sitting in my driveway. 

I did pour water on it (how simple is that idea??) and the next morning put it in the trash can.  I ponder what actually goes on in the minds of teenagers???
