A man went to a nightclub with a few friends. The bouncer refused to let the man in because he wasnâ€™t dressed appropriately. The dress code called for a tie. None of his friends had a spare tie. After thinking for a moment, one of his friends said, â€œI know! I have a set of jumper cables you could use as a tie. Just tie two ends and tuck the other ends in your shirt.â€ The man put them on, and headed back to the club. The bouncer was suspicious. But he agreed to let the man in as long as he didnâ€™t start anything.
