From Monty Python's Life Of Brian:
REG: Furthermore, it is the birthright of every man--
STAN: Or woman.
REG: Why don't you shut up about women, Stan. You're putting us off.
STAN: Women have a perfect right to play a part in our movement, Reg.
FRANCIS: Why are you always on about women, Stan?
STAN: I want to be one.
REG: What?
STAN: I want to be a woman. From now on, I want you all to call me 'Loretta'.
REG: What?!
LORETTA: It's my right as a man.
JUDITH: Well, why do you want to be Loretta, Stan?
LORETTA: I want to have babies.
REG: You want to have babies?!
LORETTA: It's every man's right to have babies if he wants them.
REG: But... you can't have babies.
LORETTA: Don't you oppress me.
REG: I'm not oppressing you, Stan. You haven't got a womb! Where's the foetus going to gestate?! You going to keep it in a box?!
LORETTA: [crying]
JUDITH: Here! I-- I've got an idea. Suppose you agree that he can't actually have babies, not having a womb, which is nobody's fault, not even the Romans', but that he can have the right to have babies.
FRANCIS: Good idea, Judith. We shall fight the oppressors for your right to have babies, brother. Sister. Sorry.
REG: What's the point?
FRANCIS: What?
REG: What's the point of fighting for his right to have babies when he can't have babies?!
FRANCIS: It is symbolic of our struggle against oppression.
REG: Symbolic of his struggle against reality.
