jQuery Fallback

var fallback = function(options){
	var numOfOptions = options.length;
	if (numOfOptions == 2){
		return (options[0].length > 0)? options[0] : options[1];
	}else if (numOfOptions > 2){
		return fallback(options.slice(1));
	}else if (numOfOptions == 1){
		return options[0];
	}else{
		return $();
	}
};
