Getting out smile

After nine month's waiting, a married young guy's wife delivered a baby girl
in the hospital.
.
The guy and his friend were in the hospital. At the hospital proud daddy was
looking through the glass window at the newly arrived babies. The nurse had
just guided his eyesight to his baby's crib.
.
The Daddy says, "Ticky, Ticky, too, too. Look, she smiled at me! Isn't she
beautiful?"
.
His friend says, "Yes, but your kid didn't smile."
.
The father replies, "I was talking about the nurse. Not the child!"
