Hah! I was never allowed to have Ken dolls either...
BUT I had a Superman doll (and a WonderWoman doll) that was all muscular and had bendable arms (that one of my friends liked cause she could make Barbie and SUperrman "slow dance" WTF?).
I had this friend and we once made our Barbies have a secret back-room prostitution ring going on behing their hair salon. They'd take customers in and then shuttle them to the hooker room. Weird!! I could have never come up witht he idea- I at the time didn't really know what we were playing, I think. My friend was a little ...mature for her years.
