Dude in a Jetpack Flies Around 'World's Most Expensive Billboard'

Energy drink Go Fast! and Skydive Dubai hired a guy with a jetpack to zip around a giant co-branded sign planted in front of the Burj Khalifa, the world's tallest building, which is located in Dubai. The clients boast that this is the world's most expensive billboard, and have floated the figure of $1.3 billion into the ether—though the fine print explains that number would be the cost of the promotion if the flight had lasted a month.
