Two pieces of string go into the White Horse pub, two pints of lager please? barman says 'sorry we don't serve string in here' , they go out rejected, 'I ain't having that' says one, he ties himself up, ruffles the ends and says to his mate lets go back in, he'll never recognise me now, they go in, ask for two pints 'aren't you the two pieces of string that came here earlier?' ....I'm afraid not....( A Frayed Knot!)....
