1x16 - Cow and Chicken

Cow has a new pair of glasses, and suddenly becomes the smartest person in school. Chicken decides that two can play at that game and gets glasses himself, but since he already has perfect vision, the glasses make everything look blurry. He soon becomes the new smartest kid in class. Because of his new intellect, he is placed in charge of tearing down the new ""dungeon"", which was really a new indoor swimming pool.
