Fishing

Three men were sitting on a park bench. The one in the middle was reading a newspaper; the others were pretending to fish. They baited imaginary hooks, cast lines, and reeled in their catch.
A passing policeman stopped to watch the spectacle and asked the man in the middle if he new the other two.
“Oh yes” he said. “They ‘re my friends.”
“In that case,” warned the officer, “There's a storm coming - you’d better get them out of here!”
“Yes, sir” the man replied, and he began rowing furiously.
