Two pieces of string are walking past a bar "Lets go in for a drink" says the first string "We cant, they dont serve string in this bar" I will diguise my self" The first string winds himself ito a tight ball and takes the fibers fom his top end and pulls them apart in wild an unruly manner, walks in and asks for a drink. " You are a string are'nt you?" " No I'm a frayed knot"
