The mechanic knocked on the door and called out: Mr. Thornnapple
Mr Thornapple: Yes, coming!
Mr Thornapple: Is my car ready?
Mr Thornapple: We've made it just like new for you, as you requested!
Mr Thornapple: WONDERFUL! You were able to fix that knocking in the engine and the squeak in the brakes and that thumping noise in the suspension??
Mechanic: No, I'm sorry. But we weren't able to repair any of those things.
Mr Thornapple looked puzzle: Then how did you make it just like new?
Mechanic smiled: We have turned back your odometer!
