Uday Hussein
In a sign of loyalty to Saddam, Izzat Ibrahim al-Douri, who was vice president of the Revolutionary Command Council, agreed to let Uday marry his daughter. But al-Douri had so much influence over Saddam that he could make Saddam promise the marriage would never be consummated.  (This means his daughter would never have to have sex with Uday.)  However, soon after the marriage, because of Uday's violent and out-of-control behavior, al-Douri quickly asked that his daughter be allowed to divorce Uday.
