S5, E12: Lillian is nervous about the city inspector's examination of her diner as well as Buddy's radio show, which will be broadcast live from 'The Yesterday Café.' Buddy is concerned that he will not be able to fill up the air time on his own, so he begs Walter and the Powell kids to help out and be his guests. The next day at the diner, the inspector arrives to check on the electrical wiring and announces that he is closing the place unless Lillian pays him off. Meanwhile, Buddy panics just as he is about to go on the air. The Powell children appear, and Buddy convinces Charles to entertain the audience.
