Back in the old Soviet Union, if you wanted a car you would have to order it several years in advance and pay cash up front.
So having gathered his money for a long time, a man goes in one day to buy a car. He puts the money down and the clerk says, "Very good comrade. You will receive your car 5 years from today.'
The man asks, "In the morning or the afternoon?"
The clerk says, "It's 5 years from today what difference does it make?"
The man says, "Well, the plumber is coming in the morning."
