Some time ago, I had been working on a big home improvement project for which I had collected a lot of lumber over the past year. One evening at quitting time, I left some of the lumber out on the porch overnight.
When I came back to it the next morning, this is what I saw:
Small, conical mounds of sawdust, all in a row. “Oh No! What is it?!?” I thought. “Carpenter bees? Enormous powder post beetles?”
Well, as it happened, it wasn’t an insect infestation at all. My daughters had come in to play in the sawdust after I left, and they had made the little piles of sawdust for fun.
This story didn’t happen on April Fool’s Day, but it was still a great (though unintentional) prank.
So the next time you want to play a prank on a woodworker, leave some little dust piles in a line right under his best lumber. Then stand back and watch him freak out.
