When I was 11 my friend and I thought it would be funny to throw water balloons at cars.
We hid in the bushes out the front of my house with a bucket of balloons, the first on I threw missed, the car stopped and this big raging dude got out screaming "WHO THE forget WAS THAT"
We legged it back in to my house and locked the doors, I hid while listening to the man scream and rage, smashing on the front door. He picked up the bucket of balloons and threw it at the front of the house before storming back to his car and driving off after about 5 minutes of pure rage.
I promised myself I would never throw water balloons at a car again, so many bricks were shat that day.
