My boss' wife Sherry was exasperated with her younger sister, who bought an unreliable car and called for a ride every time it broke down.
One day Sherry got yet another one of those calls.
"What happened this time?" she asked.
"My brakes went out," her sister said. "Can you come to get me?"
"Where are you?" Sherry asked.
"I'm in the drugstore," her sister responded.
"And where's the car?"
"It's in here with me."
