John P. writes: “On MSNBC, Chris Jansing just bragged that she needed P. Diddy to teach her how to use a hammer when she was working yesterday on the Habitat for Humanity houses that are being built near the Today Show studio.”

John’s points about Habitat for Humanity are right and correct and all that. But what adult needs to be taught how to use a hammer? I know there’s a right way and a wrong way to hammer a nail. But still, not a lot of moving parts, you know?
