Bob went home early after a night shift as a security guard and exhausted, dropped his clothes on the bedroom floor and was about to fall into bed, when he saw his wife was still in bed. "Oh, you're early!" she shrieked suddenly. "I have a splitting headache, could you please drive down to the pharmacy and get me some aspirin?"
Bob quickly grabbed up his clothes and drove to the pharmacy, where his buddy the pharmacist said "Oh, Bob! When did you start working as a mailman?"
