Better function.bind()

Function.prototype.bind = function bind(thisObject) {
    var func = this;
    var args = Array.prototype.slice.call(arguments, 1);
    function bound() {
        return func.apply(thisObject, args.concat(Array.prototype.slice.call(arguments, 0)));
    }
    bound.toString = function toString() {
        return func.toString();
    };
    return bound;
}


function foo(){return 1}
foo.bind({}).toString() //function foo(){return 1}

Whoops. Thanks!
