A Date from Heck

S2 E15: Charles and Buddy have the Powell house for themselves and decide to recruit dates. At Sid's Pizza Parlor, Charles befriends Anna, a pretty new student from Yugoslavia, who quickly agrees to come to the house and cook dinner. Unfortunately, the plans made by the Powell family are cancelled and Charles bribes Buddy to take them to a concert in the park. As the evening approaches, a thunderstorm begins, yet Anna arrives safely...with her mother, father, and brother.
