Never drop the soap in a communal shower.
If it says "free, take one!" Take two.
If you have to ask how much something costs, you probably can't afford it.
Sometimes, you have to put the "I" in team!
If you're going to be good, be very good. If you're going to be bad, be very bad.
Win if you can, lose if you must, but always cheat.
Never kick someone when they're down, unless you are absolutely certain you can run faster in the escape
