I have to disagree with CurtainPullDowner and jasonf.
Although I never really thought twice about these lyrics, I think that it's Jamie saying that HE doesn't care if she has a shaved head or once was a man.
Later in the song he sings,
"If your mother and your brother had relations with eachother
and your father was connected to the Gotti clan,
I'd say, 'Well, you know, nobody's perfect"
It's tragic but it's true.
I'd say, "Hey, hey, hey, hey, I've been waiting for someone like you."
He isn't talking about how his mother would react. Like most of the people who replied, I think he's saying that you can be ANYTHING but Jewish, and you're good.
Call me Travis. :)
