I don’t like my cell phone that much
Someone in the marketing department at LG had an idea to put vouchers to get a free phone in helium balloons, and then release them for a crowd to go chasing after. Small problem. Those phones are worth over $800, and the crowds that showed up were highly motivated. And by highly motivated I mean they showed up with BB guns and spears. The resulting chaos left 20 people injured and 7 sent to the hospital. This reminds me of the great Turkey Drop Thanksgiving episode of WKRP.
