A lady answered her front door to find a plumber standing there. "I'm here to fix the leaky pipe," he announced.

"I didn't call a plumber," said the lady.

"What?" huffed the plumber. "Aren't you Mrs. Frobisher?"

The Frobishers moved out of this house over a year ago," explained the lady.

"How do you like that," grunted the plumber. "They call you up and tell you it's an emergency and then they move away!"
