Hey Little Monster

Kevin: *walks into my room holding bizarre-looking stick
Me: What the hell is that?
Kevin: A double headed arrow.
Me: Why the hell do you need an arrow with two tips?
Kevin: It's pretty simple, really. The first one pierces the skin and then the second one enters the puncture wounds and drills into the flesh.
Me: Uh, hold up just one second. Whose flesh are you planning on drilling into?
Kevin: Wellll, let's just say it's a really really good thing that you're always nice to me and you're never mean...right?
