Duchess of Yowl: The answer to 7 Down is Feline.
Me: (counting squares) Seven letters, your grace, not six.
Duchess of Yowl: Felines. That's seven.
Me: The clue says "ice cream treat"
Duchess of Yowl: I don't like ice cream. You can just hold the ice and bring the cream. Chop chop, waitress, I'm peckish.
Me: Your grace, it's less than an hour since I served you lunch. How can you be peckish?
Duchess of Yowl: Do I question your atrocious eating patterns? You wait till noon to eat tuna!
Me: Tuna! That's four across: served in sushi bars!
Duchess of Yowl: I am the answer for everything, it's true.
