Here's a fun practical joke you can play when you're out on parole some time:
Drive up to the McDonald's drive-through speaker and order a "Chicken McBitch". The person taking your order will say, "What?" and you repeat, "A Chicken McBitch please". Then when they say, "We don't have anything like that", you drive up to thier window and dump a bagful of rabid squirrels through it.
