When you have a desire to administer a mild electric shock to your victim, reach for the Shock Pen. The Shock Pen is a starling prank that will deliver a mild electric shock to the hapless victim who tries to write with it. A good way to set up this trick is to approach the victim with a piece of paper. The paper could be a petition, a sign-up sheet, or just a blank piece of paper with the explanation for the victim to draw a circle and then you're going to show them a really good joke. When the pen is presented in this way, the victim will almost always take the pen you hand them, even if they have their own. And then when they press the button down on the pen they get a startling but harmless shock.
