I just met the coolest gynecologist. He’s an O.B.G.B.Y.O.B.
Dad's pager beeped, summoning him to the hospital, where he is an anesthetist. As he raced toward the hospital, a patrol car sped up behind him—lights flashing, siren blaring. So Dad hung his stethoscope out the window to signal that he was on an emergency call.
Within seconds came the policeman's response: a pair of handcuffs flapping outside the police car window.
