Morris, 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 Morris 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.
Morris 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 Morris. "The plumber is coming that morning."
