Listen here, you are so dumb I can smell it from here. You really think doctors can change a baby's sex? This is a play on words you little goofball. Doctors, like all humans, make mistakes, even doctors in movies. This joke implies the doctors cut off the baby's little boy parts on accident, thus leading to the conclusion that it was actually a girl, because it ain't a boy anymore. A little dark, but you know, that's why it's funny.
