I had to get a little liberal with pronunciation of the last line. I hope it doesn't break the rules. It's also not 100% valid per W3C, but works in most browsers.

I know this isn't within the rules, but I couldn't resist

var girl, attractive = true;    // There once was a beautiful girl
var boy; girl = ' World';       // And a boy who thought she was his world
boy = 'Hello' + girl;           // When the boy said hello
if (boy != attractive)          // She said 'my goodness no!'
    alert(window['boy']);       // And the boy through the window she hurled.
