var takeMeTo = function(destination) {
  var refrain = 'Won\'t you take me to ' + destination;
  return function() {
    alert(refrain);
  }
}

// Nothing happens yet, you're just assigning the anonymous function returned
// by takeMeTo to funkyTown
var funkyTown = takeMeTo('Funky Town');

// funkyTown still has access to refrain, even though takeMeTo has returned. Sweet!
funkyTown(); // alerts "Won't you take me to Funky Town"
