Do wood chips spontaneously combust?

[LBrown59]

Reminds me of one time I was on my motorcycle sitting at a stop light, and the car behind me tossed a lit cig out the window. I hopped off the bike, walked back, picked up the lit cig, said "It looks like you dropped this" and tossed the thing back in through their open window! Walked back to the bike and drove off. Don't know if it got the message across, but it really made me feel good!

With the kooks we have out there now a days this would be a good way to get your head blown blown off by some nut.
