A man was put into the jail because of murder . In the prison he asked a new comer why he was sent there. The new comer answered: "I am out of luck I think. A few days ago I thought the watermelon should be irrigated . When I was on the way to the field I saw a piece of dirty rope by the pine. I thought nobody wanted it and so I picked it up and took it home."
"But it is not against the criminal law of the federal government to pick up a piece of rope and take home!"
"I told you I had bad luck, didn't I?" The man sighed.
“Why didn’t you ask a lawyer to defended.”
"The trouble is that I didn't notice there was an ox at the other terminal of that rope."
