Fun With Porta Potties.

First, find a porta potty in an out-of-the-way place and then wait for someone to use it. While they're inside, wrap a rope around it to secure the door firmly. Then throw a piece of chain on top of it and move it around to give the occupant the impression that you're getting ready to lift it. Next, turn on a boom-box with a cassette recording of a helicopter. Turn it up gradually until it's at full volume.

Now, with the help of a few likeminded friends, lift the porta potty off the ground and move it in a back and forth motion to give the occupant the impression that the porta potty is swinging from the end of a chain that's connected to a helicopter in flight. You might even have another boombox with a cassette recording of honking geese to add to the effect a minute after fake liftoff. This may scare the **** out the person inside, but they couldn't be in a better place for that to happen, right?

After a few minutes put the porta potty back down on the ground with a jolt. Then drag the chain around on the roof to give the impression that it's being unhooked. Then gradually turn the volume down on the boombox until the sound of the helicopter fades to nothing. Then go to a payphone and call the police and report a man locked in a porta potty.
