The Man Who Sold Fish
Once there was a man who did not know how to speak english. He went to work at a fish market. The first phrase his boss taught him was:
"5 cents".
One day a customer came up to him and asked, "How much does a  fish cost?"
He replied, "5 cents."
And the customer left. The next day, his boss taught him another phrase,
"Yes, very fresh."
So one day, a customer came up to him and asked, "How much does a fish cost?"
"Five cents."
"Is it fresh?"
"Yes, very fresh," he told the customer.
And the customer left. And on the third day, his boss taught him another phrase:
"If you don't, someone else will."
So, one day, a customer came up to him and asked, "How much does a fish cost?"
"Five cents."
"Is it fresh?"
"Yes, very fresh."
"You think I should buy it?"
"If you don't , someone else will," he replied.
And the customer left.

That night, when he was cleaning up the market, a robber came and said to him, "How much is in the cash register?"
"Five cents."
"Are you trying to act fresh on me?" the robber said angrily.
"Yes, very fresh."
"I'm going to kill you."
"If you don't, someone else will."
