I have 2. the first one is dental floss.one time in a old chevy truck the rotor button in the distributor the little tab broke off in the biggest mud hole .the old lady had some dental floss in her purse,wrapped it around little tab and drove on to the house. a couple years later we broke the alternator belt and again my wife to the rescue she had panty hose on under her jeans cause it was cold out.streached them babies around the pullies and drove home and to work the next day.....
