Extra-special Water Gun

It happened again. My son had a bath and came up with something outrageous. I don't know what it is about him and bathtime. The water must get his creative juices flowing. Anyway, he came out of the bathroom grinning from ear to ear. You know what that means. He was definitely up to something. "Okay," I said. "What did you do this time?" He whipped out an object from behind his back. "I made this." I looked at that thing. It was a Johnson's Baby Shampoo bottle. And it was filled with water. "Yeah, so?" I said. "So it's a super-soaker-extra-special water gun." "It is?" I just didn't get it. "Yeah, look. Here's how it works: You aim the gun at someone, then whap the bottle really hard. The cap goes flying off, and the person gets soaked. Do you want to see how it works?" "Um, no thank you," I said. "Please keep your extra special water gun in the bathroom. It's a very dangerous weapon!"
