For my sr. prank, I went to the local pet store and bought out their entire activity of small birds. Then I stopped at the grocery store on the way to school and picked up a loaf of bread.I had a couple friends in on the gag who’s jobs were just to keep the principal busy in the school all day, and away from his brand new SUV. The key to this is to make sure that you have a REALLY good distraction for when he first gets there. You don’t want him to have time to lock the doors or turn on the alarm on his car.After that just roll down the windows just a crack, toss in the loaf of bread and add a small bowl of water, and permit the birds go inside the car. Preheat the car to about 85-90 degrees and permit stand for 5 to 6 hours. (make sure that you leave the water in the car and the windows unsmooth slightly, otherwise the birds die and you get hit w/ a pretty good fine for animal cruelty)If this doesn’t sound like something you’d want to do, ask your parents in a VERY subtle way if they’ve ever pulled any pranks. I actually got the idea for this one from my mom… I just wish that she’d told me that one of the people that had helped her with it when she was a senior, grew up to be the principal that I pulled it on. lol....................
