Pranksters on YouTube are a dime a dozen, but the guys at JStuStudios know how to stand out from the crowd. They might not have the most followers or biggest budget videos, but what they do have is far more valuable – pranks that are actually funny. Unlike the web’s ever-popular “social experiments,” they test their pranks on real, unsuspecting individuals, not actors who are paid for reactions. Furthermore, they don’t humiliate, tease or harm anyone for easy laughs. Whether they’re eating loudly in a college library or asking strangers for help finding grocery items that don’t exist, their originality always leaves the audience laughing. And this video is no exception. What they’ve come up with is so simple, yet totally effective. We never would have guessed that a glass of water could completely incapacitate someone, but it does, in the most hilariously awkward way. This is one prank we can’t wait to try out on our friends!
