I found it right here.
By now you've heard the cookie joke. You know: a CEO, a tea party member, and a union worker are all sitting at a table when a plate with a dozen cookies arrives. Before anyone else can make a move, the CEO reaches out to rake in eleven of the cookies. When the other two look at him in surprise, the CEO locks eyes with the tea party member. "You better watch him," the executive says with a nod toward the union worker. "He wants a piece of your cookie."
