A Russian man saves his rubles for twenty years to buy a new
 car.  After choosing the model and options he wants, he's not
 the least bit surprised or even concerned to learn that it will
 take two years for the new car to be delivered.  He thanks the
 salesman and starts to leave, but as he reaches the door he
 pauses and turns back to the salesman "Do you know which
 week two years from now the new car will arrive?" he asks.

 The salesman checks his notes and tells the man that it will
 be two years to the exact week.  The man thanks the salesman
 and starts out again, but upon reaching the door, he turns back
 again.

 "Could you possibly tell me what day of the week two years
 from now the car will arrive?"  The salesman, mildly annoyed,
 checks his notes again and says that it will be exactly two years
 from this week, on Thursday.  The man thanks the salesman
 and once again starts to leave.

 Halfway though the door, he hesitates, turns back, and walks
 up to the salesman.

 "I'm sorry to be so much trouble, but do you know if that will be
 two years from now on Thursday in the morning, or in the
 afternoon?"  Visibly irritated, the salesman flips through his
 papers yet another time and says sharply that it will be in the
 afternoon, two years from now on Thursday.

 "That's a relief!" says the man.  "The plumber is coming in the
 morning!"
