also as a joke you or one of your friends should ride a bike in front of the principals car. Since he's going to be in a huge rush trying to get in to the school hell will write you a check for the cost of the bike, but inevitably he will forget to write down an amount! Once you realize this take out millions of dollars from his account, buy a mansion full of super cool toys, get in trouble with russian gangsters and then when everything seems to be falling apart your parents will come and save the day.
