From the Times' coverage of the Anthony Weiner mess:

"I would think everybody knows their undergarments," said Cori Attias, 46, of Mill Basin, Brooklyn, who said she would be able to recognize a picture of herself based on the underwear alone. "It would be weird if he didn't know. It's either, 'Yes those are my boxer briefs,' or 'No, they're not.'"

I don't know about you, but I'm not sure I have all my 'undergarments' (I love that word, makes me feel like Jane Austen when I use it) committed to memory. Yet another damn thing to do.
