Cervix

Robert: It just seems like there’s a lot of interesting things happening lately. Like, I read this article about a vaccine that will completely cure a certain form of cancer.

Robert: Doesn’t do me much good, of course, because you have to be a girl to have a cervix.

Me: Well, uh.. actually, I should tell you that I have a cervix.

Me: It’s in the fridge, behind the mayo. Don’t knock it over.

Robert: I can’t believe…. No, wait. I can believe that you have a cervix. You jackass.
