In the episode where Phil and Lil are separated, and trying to find each other, Lil and Tommy go out back, in attempt to go under the fence to get to her yard. When she puts her head between her legs to see which house is hers, she says that hers is the one that looks like a choo-choo upside- down. You can see that there is a house to the left and the right of Tommy's house. But at the end of the episode, you can see Tommy's house, Phil and Lil's house next to it, and on the other side of it, where another house used to be, is a street.
