A strange case of a prank gone awry. Two men rushed onto the field during a rugby match wearing nothing but the logo of Vodafone, a mobile phone company. The logo was painted on their backs. Amazingly, Vodafone had actually approved the stunt. The presence of the streakers caused one of the players to miss a penalty kick. On the subject of odd forms of 'guerrilla marketing,' here's a website that claims it will connect you with corporations who are willing to pay you to wear a tattoo of their corporate logo. They're called tADoos. It's a hoax, of course. But it's not original. NPR presented this exact scenario as an April Fool's Day joke back in 1994.
