JS Arrays Challenge

I'm not sure what I'm doing wrong here, it keeps giving the error "Missing the unshift and firstWord variable". Help anyone?

      var spareWords = ["The","chimney","sweep's","dog"];
      var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"];
      var firstWord = spareWords.shift();
      var lastWord = spareWords.pop();
      saying = firstWord.unshift(1);

The challenge is asking you to add the firstWord variable to the beginning of saying. saying is an array, so you use the unshift() method on it, and pass the variable you want to add:

saying.unshift(firstWord);
