Lars' lost ears
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Lars pulls out his mobile phone and pretends to use it to cast a series of selfies to the in-studio screen. After they have been on display for a while, he reveals that the thing he loses most is his ears. He says that they disappear in every selfie he takes, so he's had to start turning his head to one side, when taking photos of himself, to prove that they exist. Bård awards him first place.
