That's funny Jon,...
I actually had one puff and catch on fire several years ago on a foamie after flying.
I recently crashed a plane. At the crash site, picking up the parts, I absentmindedly put the rx lipo in my pants pocket so I wouldn't drop it. The connectors had been jerked off in the crash so the leads were bare. Yep -you guessed it, things got exciting before I could get the now shorted pack outta my pocket.

I looked down and saw smoke coming out of my pocket.
