Just $24.95 seems like a small price to pay to turn your iPhone into a Taser in order to send 90,000 volts of electricity coursing through your two-timing boyfriend's body. But maybe I'm just partial to Jackass-style attacks. It turns out, though, that a product recently marketed as the "StunFone," a handy snap-on device that makes the iPhone a non-lethal weapon, is actually a hoax. (My dumb phone probably couldn't even shoot pepper spray.) The product demo got a lot of ink and views, probably because people could think of a million and one uses for such an item and wanted it to be true. (There was a halfway believable backstory.) In fact, it's a promo for Stun Creative, a boutique ad agency in Los Angeles that recently worked on promos for Conan O'Brien's late-night TBS talk show. Looking forward to the StunFone encore, though it'll be tougher to fool people next time around.
