Where did I leave my pants?

I would have been about 9 or 10 at the time, so no sexual connotation to losing my pants here... One of the first times I went skidooing as a kid, I ended up on a short sleigh towed behind 'Uncle Ben' on the skidoo because my two sisters wanted a ride and there just wasn't room on the skidoo for me too. A short distance from the house you had to go through a slight ditch and a hedge to get into open field. The break in the hedge was no big deal for the skidoo, so away we went... However, it was a bigger deal for me on the sled behind as there were several stumps of old hedge sticking up a few inches. As I was towed through — quite quickly, since the skidoo was already out of the hedge and on flat ground — my snow pants caught on the poking out sticks and proceeded to strip me clean of the snow pants, trousers, long johns, socks and boots and left me in my undershorts. Not so bad except for it being well below zero and Uncle Ben accelarating through the snow. It took about a half mile before they noticed something amiss, and a wee bit more time to defrost my cheeks...
