[London is opening a fashion boutique.]
Mr. Moseby: How's the boutique business coming, London?
London Tipton: it's going to be fabi! I'm putting purses over here and matching belts over there.
Mr. Moseby: And do you have a business plan?
London Tipton: Weren't you listening? I'm putting purses over here and matching belts over there.
Maddie Fitzpatrick: No, no, he's talking about financial planning. Ordering stock, taking inventory...
London Tipton: I said, I'm putting purses over here and matching belts over there.
Trivia: London Tipton was supposed to be somewhat named after Paris Hilton. London and Paris (both cities) and Tipton and Hilton (Hotels).
Question: What Happened to Muriel? Around season two she disappeared.
Answer: Keep in mind, Muriel wasn't very popular. So the writers/directors must have thought it'd be a good idea to let go of the character. No one seems to be complaining.
