Would it be wrong of me to steal my son's brand-new birthday present?

Today was Arie's birthday party and one of the kids game him a blowdart gun that shoots foam darts (and is pretty damn accurate to boot). I know I should probably be thinking "but it's a gun" and wish that the kid hadn't given it to him, but Goddamn is that thing fun. Really. I only got to use it one time and already I'm thinking of how I can get it away from him. There is seriously something insanely satisfying about blowing air through a tube as hard as you can and not even being able to see the dart fly out until it's hit its target because it's going so fast. I want to have one for myself so I can sneak around the house, hunting down the cats and the dog with it. Or else I could sit with my feet up on the couch and any time the boys started bickering with each other, I'd blast 'em with my dart gun. Now if I could only add some sort of tranquilizer to the suction cup, then I'd have the ultimate parenting tool. Oh well, I can dream (and eventually he'll grow bored with it -- then it's mine!).
