A baby was just born. He had all his fingers and toes and looked quite normal, except that he was laughing like crazy.
All the doctors and nurses were examining the little thing, in front of the worried parents, but he kept on laughing, his tiny fists all closed and tears rolling from his eyes.
One at a time, a pediatrician unfolded the tiny fingers to check if the hand was all right, and... guess what he found?
The birth control pill!
