While we’re not 100% sure this qualifies as a scientific breakthrough, this six-second video of a baby laughing at the misfortune of two young skateboarders seems to suggest that it is instinctually hilarious to humans when other humans suffer. No matter your age or athletic ability, if someone, that’s not you, crashes, slips or falls down, someone, somewhere is going to laugh.
As you go about watching this video for the fourth, 10th, 37th time, try to think of it as its own scientific experiment. Now, do you find yourself laughing at the fail or the baby laughing at the fail? Please email us your results in the form of a comment or by sending a handwritten thank you letter to YouTube dot com. Don’t worry, they’ll let us know when it arrived.
