Swallowed a contraceptive

The tired doctor was awakened by a phone call in the middle of the night.

"Please, you have to come right over," pleaded the distraught young mother. "My child has swallowed a contraceptive."

The physician dressed quickly; but before he could get out the door, the phone rang again.

"You don't have to come over after all," the woman said with a sigh of relief. "My husband just found another one."
