This is an ad for something called Pull-Ups training pants, apparently a sort of knee-length Depends for preschoolers. Headline: "You know what they say: `Small feet, small bladder.' " Oh, really? We conducted an informal survey around the office and we found absolutely no one who had ever heard this delightful aphorism. We did, however, strike up a promising friendship with an intern who has a urinary tract infection. But never mind that. And never mind this ad. Just supply a new maxim that involves any internal organ and any bodypart, to sell the product or service of your choice. Unzip your mind at email@example.com. Contest not open to anyone who's ever stood up and announced, "Excuse me, I have to micturate"!
