 When Rocky throws a party and the chickens are dancing, the two rats  appear wearing Ray Ban Butterfly sunglasses, the same model and  brand used by The Blues Brothers. They also do a little dance  impersonating Joliet Jake and Elwood Blues. The song they dance to,  Chuck Callhouns "Flip, Flop and Fly", was a standard on the bands  set, and they released it in four of their albums.
