Ernie, Bert and Rubber Duckie are about to travel through the treacherous Duck Cave to find the Wise Old Duck and ask him a very important question. Using their map, they come across the first landmark of the cave – The Feather Tunnel, which causes anyone who touches the feathers to laugh. Next, they swing across the Great Egg Pit. Finally, they find a large duck egg, which means the Wise Old Duck is near. The Wise Old Duck emerges and Ernie asks the question: “Which came first – the Duckie or the egg?” The WOD cannot think of an answer, as Bert accidentally knocks over the large duck egg and it begins to roll. They all escape and Ernie realizes the answer to his question: to him, Rubber Duckie will always come first.
