Ok, I have created a category just for crazy ideas. I can't help it. I have too many of them to let them slip away. If you ever use an idea, I hope will at least drop me a line or a photo.

Instructions:
1. Get a few good pictures of a gasoline pump, especially the instrument that you use to pump the gas (aka the handle)
2. Create a model of the pump handle.
3. Attach a ripped rubber hose to the handle.
4. Insert into gas tank of car.
5. Drive around and see people's responses.

Special Note: It would not be a good idea to drive around with the gas tank open, so with some ingenuity you could find a way to make it "appear" that you drove off from the pump and the gas pump handle was ripped off. Maybe you could use suction cups, or in some way secure it to your car without actually opening the cap to your gas tank.
