Mr. Jones has been saving for a car for a long time and he is finally able to go to the car dealership to arrange a delivery date. He has chosen a Chevy Naseem, a modest sedan. Six months later the dealer calls him and says "I have good news, your car will be ready twenty years after next Thursday."
"Excellent!", said Mr. Jones. "Morning or afternoon?"
"Does it matter?"
"Yes. The plumber is coming in the morning."
