A DOSE OF HIS OWN MEDICINE

This woman is in labor.  Everything is going fine, and suddenly the nurse exclaims,  "I can see his head!"

Sure enough, the baby peeks out, but then he sees this nurse, gets scared, and ducks back in.

After a few moments, he pops his head out and looks around the room again.  This time, he sees the doctor, gets scared, and ducks back in.

A few more minutes pass, and the baby reluctantly peeks out again. This time, he sees his father.

Suddenly, he reaches out and starts poking the father on his forehead and says,  "How do you like that, asshole?!?"
