Hi ella,

You need to add the lastWord to the end of the array, to do that you use .push()

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.unshift(firstWord);
saying.push(lastWord);
