By now, you've probably seen the fake Puma ads-in which an anonymous girl kneels in a rather suspicious position facing an equally anonymous guy (in her Puma sneakers) and, upon closer inspection, it looks like there's something sticky on her thigh. If not, look now, because Puma is threatening legal action against anyone distributing the manipulated photos. The company's most successful viral marketing campaign, and they're trying to shut it down. Puma's hunting down the maker, who has to be a Brit, says a Puma official. Just because. If the Puma photoshop artist is reading this-and, let's be honest, you're checking the web every five minutes and loving this-please send us an email. Dirty minds want to know: what inspired you?
