You can become a fan of Episcopal Priest Barbie on FaceBook.
(Disclaimer: I am fairly certain the only way you can actually have an Episcopal Priest Barbie is to make your own damn vestments for your existing Malibu Barbie. Results may vary.)
UPDATE: Everyone's in on the action! Meet Tefillin Barbie, Atheist Barbie, Muslim Barbie, and Butch Dyke Barbie.
