Where's the basement?

Abbey and I were watching Mister Rogers' Neighbourhood this morning (a delightful episode where Purple Panda dresses up in a dinosaur costume, and then Fred takes a trip to the Carnegie Museum of Natural History--right here in Pittsburgh--to show off the Hall of Dinosaurs) and by the end of the episode, Abbey was confused.

Abbey: Why is he taking off his shoes?

Me: He's leaving his play shoes there and putting his fancy shoes back on.

Abbey: Why is he taking off his sweater?

Me: Because he keeps his sweaters there for play. He wears a sports jacket back to his house, see? (pointing to the "lovely" powder-blue blazer that men of Fred's generation seemed to favour)

Abbey: Maybe it's a vacation house.

Me: Why do you think so?

Abbey: Because it doesn't have a freezer* and I didn't see a door for the basement. Maybe I missed that part of the show? Or maybe the basement is underground somwhere?

Me: Maybe!

Did any of you ever wonder where the "rest" of Mister Rogers' house was? I assumed he slept on the sofa, but I did wonder where his bathroom was!
