According to the expected output, you'd need something like:

    function say(x)
    {
    	return function (y) { alert( capitalize(x) + " " + capitalize(y)); }
    }

Where capitalize makes the first character uppercase.

Oops, that's a type-o. The capitalize doesn't need to change.

Thanks for the heads up.
