Doctor VS Druggist

An older man strode in to his doctors office and said, "Doc, my druggist said to tell you to change my prescription and to check the prescription you've been giving to Mrs. Smith." "Oh, he did, did he?" the doctor shot back. "And since when does a druggist second guess a doctor's orders?" The old man says, "Since he found out I've been on birth control pills since December."
