The man who saved the life of Lisa's uncle moves in on the Douglases seeking repayment for his good deed. Lisa feels an obligation to help Lazlo, but Oliver is simply irritated by his constant money-grubbing. Oliver's also unfazed by Lazlo's threats to cast a Hungarian curse on him.

At Sam Drucker's store, Oliver and Lisa meet their new neighbor, who is also expecting. She decides it's time, so Oliver offers to drive her to the hospital. Once back home, Lisa had already offered to "sit" with her other 4 children...and Eb. Oliver doesn't mind at first, but quickly changes his mind after the kids break dishes, run amuk in the house, and when he is forced to sleep in living with the boys, while Lisa, Ralph, and the other girls sleep in the bedroom. Things are even worse when Oliver finds himself drive each kid to school at a different time, then having to turn right around and pick them up a different times. Later that night, it's a wild goose chase at the drive in as each kid ends up getting lost. The day they finally have to go home, they end up staying longer after one of them catches the measels from Ralph.
