This one is pretty funny; I tried it myself last April Fool's Day.
Get ahold of your stooge's car keys. Roll up all windows except one-- leave this one open about two inches. Feed a steady stream of styrofoam peanuts into the stooge's car. Do this until the car is totally filled with peanuts (you'll need a whole lot).
Next, approach your stooge and present a reason for using his car (ask him to buy something for you). Sit back and watch the fun.
