A string walked into a bar and ordered a shot of scotch. The bartender said. “I’m sorry, we don’t serve strings here.” The string left, went to an alleyway, tied himself into a knot and messed up his ends. He walked back into the bar and ordered a shot of scotch. The bartender said in a loud voice, “ I ALREADY TOLD YOU, WE DO NOT SERVE STRINGS HERE! YOU’RE A STRING AREN’T YOU!” The string replied, “ No. I’m a frayed knot.”
