1. Get some clear plastic wrap and completely cover a door way. Be sure to set up a camera to capture the face as your mom or dad walks into it.
2. Set your parents alarm clock to 2 hours before it's actually time to wake up, then set another one for 1 hour before it's time to wake up. They'll go back to sleep after the first one, but the second one will really get them up!
3. Empty out your moms' shampoo bottle and put baby oil in it. Make sure your mom has a huge sense of humor, or you'll be yelled at for days. Baby oil doesn't wash out really easily!
For our Halloween Prank we fixed up a life size dummy to look like a trick or treater complete with bag of candy and hidden microphone. Then we went door to door with our fake "Timmy" to see what kind of reactions we would get.
