Dance with Me, Herman (S01E22)

When Lily accidentally finds an invitation to a school dance in Marilyn's dresser drawer, she wonders why her niece didn't invite the family to the event. Lily questions the girl at the dinner table and discovers that Marilyn did not want to embarrass her uncle Herman by forcing him to attend a dance when she knew he was unable to dance well and didn't really care for dancing. He tells the family that he intends to take dancing lessons and make Marilyn proud of him when he attends the event. (iTunes)
