First Aid
"It was awful," she explained. "I was walking down Elm
  Street and there was a terrible accident. A man was
  thrown from his car and he was lying in the middle of
  the street. His leg was broken, his skull was fractured,
  and there was blood everywhere. Thank God I took that
  first-aid course."

  "What did you do?" asked the bartender.

  "I sat down and put my head between my knees to keep
  from fainting!"
