The gang returns from their latest trip to Vegas, which Matt expected to be an elaborate celebration of his recent retirement, wholly forgetting what flakes and cheapskates his friends are, and that they really don't care about his personal life. There is drama, excitement, bus rides, plastic horse racing, magic shows, "healthy" food, cheap gaming, and fancy dressing, featuring the return of Sigma Derby Expert Ski, and a new Sigma Derby-themed song.
