i came, i saw, my pants split

This holiday I have been doing quite a bit of home-improvement, playing with rivet gun, screwing things (not people), hammering nails, fixing stuffs.

So just now I was sawing a wooden plank with a hand saw when I heard some tearing sound... couldn't be from the wood since my hands weren't sawing already... then suddenly I felt a cool gush of air from "behind".

Some materials (such as those found on your shorts and pants), you don't need to saw it to split it.
