Remember, boys, after urinating, make sure you use your elbow to flush. That way you don't get everybody else's pee pee germs on your hands.
Always properly stock your masturbatorium with washcloths. You dont want to grab that kleenex cuz you'll be picking off that concrete combo of spermatazoids and tissue paper for days!
Never, ever hit on your spouse's sister or mother. Even if Lil' Miss Inlaw is pushing the issue. It will always end in disaster... (although the sex with her sister might be worth it) The cousins, however, are 'Free Range'.
