"A Hermaphrodite Baby" joke

A woman gives birth to a baby. Afterwards, the doctor comes in, and
says, "I have to tell you something about your baby."
The woman sits up in bed and asks, "What's wrong with my baby, Doctor?
What's wrong?"
The doctor replies, "Well, now, nothing's wrong, exactly, but your
baby is a little bit different. Your baby is a hermaphrodite."
The woman looks a little puzzled, "A hermaphrodite... what's that?"
The doctor says, "Well, it means your baby has both the... er...
features... of a male and a female."
The woman turns pale. She exclaims, "Oh my god! You mean it has a
penis and a brain?"
