Lars' failed Morse code
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Lars brings in an airhorn, with ear defenders and (for some reason) a hard hat, sits on the floor, and tries to honk out the message "Oi, oi, oi, you big alpaca!" in Morse code, using a guide sheet he's also brought with him. He only gets as far as "OI OI" before Bård interrupts him to state that he knows what he's trying to do (Bård apparently has a good knowledge of Morse code), but he's not doing it very well. Lars realises that his effort is weak, in comparison to all of the others, and asks if he can stop, acknowledging that he has definitely lost the task. Bård lets him return to his seat, and awards him an appropriate last place.
