About the craziest prank that we've ever done is putting a sleeping friend's hand in a bowl of warm water. It didn't work. Not only did he not piss his pants, but when he got thirsty in the middle of the night, he drained the entire thing without leaving the bed. Ouch. Luckily for us, the future has brought far more hi-tech ways to scare the bejeezus out of people.
Like this modern-day take on a classic prank, carried out by some guy's uncle. He's got a point: why go to all the trouble of dressing up as a ghoul and scaring people, when you can just attach some stuff to a drone and freak out the whole neighborhood! Welcome to the future, when you can pull crazy pranks without leaving the comfort of your living room.
