I can't recall which episode, but there is a very funny scene in which Lois is ordering shoes by phone from a catalog. She goes through a whole litany of numbers: shoe size ( I beilieve it was 7), catalog number, credit card number etc...and then she is told that the shoe is out of stock. I seem to remember that it was quite a coup on Teri's part to finally get all the numbers right and the scene in the can.
Perhaps someone remembers which episode that was.
