Feminism: Er, any reason why women can't vote?

Feminism: Ta very much. I'm voting for equal pay.
Patriarchy: Equal pay? Don't be ridiculous! We can't afford it!
Feminism: Now who's being daft? Come on, equal pay or you don't get equal work.
Patriarchy: You're so demanding all of a sudden! Get working!

Feminism: How about you take a running jump, creep?
Patriarchy: Frigid old prude, that's what you are. I'm divorcing you.
Feminism: No, I'm divorcing you. I voted for that too, remember?
Patriarchy: If you leave me, I'll surround myself with luscious female teenage flesh! That'll make you sorry!
