3 Words You'll Never Hear Together

I heard this game on a morning show years ago and have always thought it was clever. The idea is to come up with words you'll never hear together.
  1. Those lucky Kennedys.
    This was the example they used. I have never forgotten it.
  2. What delicious lutefisk!
    I don't even really know what this is. Being from MN I just know it's gross.
