A woman goes to the hospital, and her doctor gives her a sonogram.
He sees the baby
and suddenly the baby says: "Are you my daddy?"
The doctor is shocked and goes to get another doctor, who looks at the sonogram.
The baby says again: "Are you my daddy?"
The doctor says: "No, I'm not your father
They go to get the dad, the father looks at his baby boy and the baby asked: "Are you my daddy?"
And the father says: "Yes, I am!"
So, the baby pops out of the mother's womb, picks up his hand, and starts poking the father in the head while saying: "How do you like that?! How do you like that?!"
