Dan was the doorman of a club in a big city.
Everyday, thousands of people passed his door,
and a lot of them stopped and asked him, "What's the time, please?"
After a few months, Dan said to himself, "I'm not going to answer all those stupid people any more.
I'm going to buy a big clock
and put it upon the wall here."
Then he did so.
“Now people aren't going to stop and ask me the time," he thought happily.“
But after that, a lot of people stopped,
looked at the clock and then asked Dan, "Is that clock right?”
