How could I be mad?

I'm on my computer trying to file my very late quarterly sales tax and my sweetie is sitting below me playing quietly.  He has a habit of emptying my drawers full of scrap supplies.  Anyways....I turn around and find this.  Initial madness...turned into laughter...grabbed the camera.   Although, this isn't the first time he has done this, but I guess he is only a child once....and it was his birthday.
