The Super Stunt

From Zug.com:

During the second quarter of Super Bowl XLI, a team of elite, highly-trained pranksters quietly distributed 2,350 packets to the lower east section of Dolphin Stadium. These “Party Packs” contained a six-inch light-up necklace, along with official-looking instructions. By wearing the necklace lights during the halftime show, Super Bowl fans believed they would be spelling out the word “PRINCE.”

But they weren’t. They were spelling a secret message that was broadcast to 93.1 million people around the globe.
