In the Key To Her Heart mission for Woozie in Las Venturas, when you go to the courtier's house and kill the gimp, you can take his purple dildo to use as a melee weapon. Additionally, when you get Millie as a girlfriend, instead of dating her, kill her. Wait awhile and Woozie will call. CJ will say that Millie is dead. Woozie will tell you to go to her house and take the pass key.
