The Wrong Direction

DOCTOR: "Mr. Johnson?"
JOHNSON: "Doctor, yes, is everything okay?"
DOCTOR: "Well, the birth started a little earlier than expected, too soon for a traditional birth, so we had to go with a c-section. Your wife is recovering from surgery, and you are the new father of a healthy baby boy."
JOHNSON: "I'm a father! Oh, thank you, Doctor!"
DOCTOR: "APRIL FOOL'S DAY! Ha ha ha, I was just kidding with you about the c-section, Mr. Johnson. Your baby's dead."
(Doctor exits the waiting room, whistling)
