Ahh, nothing wreaks of good old juvenile tomfoolery than simple, cheap pranks on those with whom you live with.  Remember that picture where some wise-guy drew on your face with Sharpie while you were passed out?  This Instructable gets you one step closer to redemption and all it will cost you is about 7 cents +/- (which you may get back).

Let me start by setting the scene:  your jerk roommate is in his/her room asleep or otherwise not paying attention; their door is closed.  You are about to exact revenge with ninja stealth.

Step 1: Lock Without a Key

The point of this prank is to lock someone in a room, usually causing significant confusion as to what is wrong with the door and/or handle.

Start by pushing in the door near the top.  Slide several pennies into the crack between the door and the jamb molding about 18" above the handle.  Repeat process below the handle.  Keep adding pennies equally to the top and bottom until you can't squeeze another one in.
LOL we used to do this to each other all the time when I was in college living in the dorm! Great fun!
It's more fun to loosen the handles - you pull your side off, remove the bar and they're locked-in.<br> <br> L
That only works if the screws are on the outside.
its cheap and simple! awsome! :)
