An Irishman and an Englishman had neighbouring sheep farms. One day the Englishman called the Irishman and said: ?One of your sheep has been caught by the leg in one of my bear traps, you?d better come and take it home.? ?What makes you so sure it?s one of my sheep,? The Irishman asked. ?Well? said the Englishman, ?It has gnawed off three of its legs but it?s still trapped???.?
