They might seem cute but be on guard at all times! Like any child they come pre-made with built-in pillage and hyperactivity, but unlike the more submissive Girl model, boys are ten times more hazardous. They are classified under Feminist male-species nomenclature as Rapists In-Training--their rape proclivities not yet refined beyond stuffy-humping and Barbi de-clothing, they typically make their first rape attempt by 14. Apparently many are being knighted for the evisceration of known pedophiles Michael Jackson, Galactus, and Captain Planet. All known members of NAMBLA.
In the meantime, boys think they are badass, but really they are just idiots. This is contrary to girls, who are both mature and fashionable. With boys though, their idiocy starts early, usually by kindergarten, and gets worse over time. By the time they are ten most of the damage has been done on what little is left of the known world, and when puberty sets it's complete. This is called the "Chronic Boy Evisceration Syndrome," which is said to affect roughly 1 out of every 2 kids, and affects boys almost 100% more than girls. There is no known cure.
