Another classic, great for dorm rooms. When your mark is inside their room with the door closed, simple take a bunch of pennies and pack them as tightly as you can between the door and the door frame. The pressure from the pennies will in essence lock your mark inside their room. Only when these pennies are removed from the outside will your mark be able to leave their room. Gets them especially mad when they try to leave and they are already late for class. And even college students can usually get their hands on a handful of pennies.

Of course you never want to penny-in your mark and leave just in case there is a fire or other emergency. But you are right, this is an easy and effective classic practical joke!
