I'm posting this one for my Grandad!  I think he'll get a kick out of this!

You learn something new everyday, but this new trick just might be the best thing you'll learned all year! Watch this carpenter teach us how to get nail through wood without unnecessary holes.  He dips a piece of wood into boiling water and lets it sit for two days. The piece of wood looks contorted and worthless until he does the exact same process again. Viola! An awesome trick to pass down to your children! If I hadn't seen his process before, I'd think it was magic!
