1.)  Boobies rule.  You can play with them for hours - contort them into strange shapes, and they always bouce back to the original position.
2.)  Ass.  You cant go wrong with a perfectly shaped rear end.  That little area where the bottom of the buns meets the legs is key.  If I cant bounce a quarter on it, shes out of luck, damnit.
3.)  Legs.  Very important.  Im not a soccar fan, so if you played, get your tree trunks away from me Amazon Girl.
4.)  Personality.  Is she gonna be a Plain Jane Missionary dame?  Or is she gonna make me feel like Im 15 again?  Loud, obnoxious, violent, and extra points for the ability to scream and insult me in a forgein tongue.
