Water Balloons and cop cars

I was sitting in the living room a few weeks ago, Quinton and Jerrod were outside, cooling off with water balloons. I heard some tires squeal, car door slam and "GO GET YOUR MOTHER"

Of course, I went to the door to find that my dear children were throwing water balloons at passing by cars.

They were lucky enough to strike an unmarked cop car!!!! When will they learn?

Jerrod informed me quickly that he wasn't throwing them, he was just the "lookout" Quinton said, "so much for looking out" Jerrod replied, "you told me to look for open windows, not cop cars"
