Ever tried nailing at a slight angle so the nail pulls the corner tight instead of pushing it apart? Learning that trick cost me about three face frames, so you're not alone in the splinter club.

Oh man, the fake rock photo is the best part because every conspiracy guy has that one uncle with the one photo that proves it all. I mean, here's the thing, if NASA really faked the whole moon landing in a studio, they would've needed thousands of people to keep quiet for over 50 years, and we all know humans cannot keep secrets like that. Somebody would've spilled it for a book deal or a talk show spot by now, guaranteed. Your barber is probably just messing with you or his uncle was messing with him back in the day. Also, a photo of a rock doesn't really prove much, it just looks like a rock, and plenty of real rocks look fake too. Maybe it's just me but I'd ask the barber to bring the uncle in person and see if the story holds up.
