I can picture doing that with a work light!
But I only burned my dad once.
In the car going to church - I went to turn off his choice of what he selected on the radio - knocked the cigarette out of his hand onto his brand new, expensive, dress pants - burning a series of large holes.
man was he mad.
I sat in church wondering whether or not I should turn him in for using the lord's name in vain.
Needless to say I left the radio alone from that day forward.
