It's An Old Joke and One of My Favorites

We were having dinner tonight and Carter was looking at his Solar system placemat and explaining to me about all of the inconsistencies and downright errors.

Carter: Like Pluto's orbit intersects Neptune's!

At this point, Olivia leans over and examines the placemat.

She points to the Earth and completely deadpan says: You can see our house.

Even Marshall busted up over that one.

Funnier still: Carter actually looked for the house before he realized she was joking.
