Lars holds a firework in his ass

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

After thinking for a while, Lars asks if there are any sparklers he can use. He is then seen standing with a sparkling firework held between his bare buttocks, and holding a golf club. After Olli lights the firework, Lars takes a swing at a ball with the club, in order to register a high speed with the camera. The camera registers the speed of Lars' ball at 39 kilometres per hour, placing him first in the task.
