The prank shows in the United States are bland as oatmeal when matched up against the stuff that comes out of Japan. It seems the Japanese prank shows are in a perpetual battle to see who can come up with the most extreme gags, and a recent shenanigan featured on a program called "Dokkiri Award" may lead the list of most insane.
In the above video, which is all in Japanese but it doesn't matter one bit, a comedian named Toshiaki Kasuga is sleeping in a cabin near Mt. Fuji. At some point during his slumber, a team sneaks in, straps him to his bed, and attaches his bed to a massive two-crane slingshot.
Then, after a 10-second countdown Kasuga has his world absolutely rocked. Fireworks ignite beneath the bed, and as he looks around perplexed the bed blasts straight through the cabin's roof and 150 feet into the air.
The camera angle which captures the close-up of Kasuga's face is priceless.
