A baby was just born.  He had all his pieces and looked quite normal, except that he was laughing like crazy.  I mean laughing real hard.

All the doctors and nurses were examining the little new born in front of the worried parents, but he kept laughing.  He laughed, hands in tight fists, until tears were rolling down his cheeks.

During the initial exam, the pediatrician slowly unfolded the tiny fingers to check if the hand was all right.  Nobody in the room believed what was found in the baby's hand.

A birth control pill!
