Jill's car was unreliable and she called John for a ride every time it broke down. One day John got yet another one of those calls...
John:
"What happened this time?"
Jill:
"My brakes went out. Can you come get me?"
John:
"Where are you?"
Jill:
"I'm in the drugstore."
John:
"And where's the car?"
Jill:
"It's in here with me."
