A guy went to enter a night club but was refused entry because he did not meet the dress code. A tie was a requirement. He thought for a moment then went back to his car. He grabbed a jumper lead and tied it around his neck in the tidiest windsor knot he could. He went back to the night club and pointed out that he now had a tie. The guy on the door now had no grounds to refuse him entry. "I'll let you in on one condition. Just don't start anything".
