Black humour for a blue Fool's Day,

A woman successfully gives birth after several hours of labor. The doctor takes the baby and leaves the room to perform some tests. Several minutes later, the doctor returns with the baby in his arms and then suddenly begins to punch it, kick it, throw it about the room and slam it against an adjacent wall. The woman screams, "OH MY GOD WHAT ARE YOU DOING TO MY BABY?!" To which the doctor replies, "April Fool's! It was already dead!"
