Laughter is contagious, but in this Berlin subway car, it’s a virulent disease. Watch as it infects every single person on the train below:
Just what are they laughing at?
Nothing, it turns out. Laughter for laughter’s sake is the goal of the Berlin Laughter Project, which orchestrated the event in a sort of flash-mob-meets-performance-art event. The absurdity of the laughter puts everyone on the train in stitches, elevating a dreary commute to an endorphin-boosting ride that leaves its passengers — and the video’s 1 million-plus viewers — grinning.
For the BLP, the laughter isn’t just for fun — they consider it therapeutic, “a powerful antidote to stress, pain and conflict.” And as a way to cheer people up on their commute. It’s a lot funnier (and warmer) than the annual pants-off Metro ride.
