jsFiddle doesn't recognize classes?

Originally reported here: Why is my jsfiddle Javascript class not defined?

However, upon my implementation, I'm seeing similar behavior but none of the answers appear to apply.

foo();
baz = new bar();
baz.getMessage();

function foo() {
    $('#foo').html("I am foo.");
}

function bar() {
    this.message = "I am bar.";

}
bar.prototype = {
    getMessage: function() {
        $('#bar').html(this.message);
    }
};

Firebug reporting: "TypeError: baz.getMessage is not a function."
