Now that Nancy and Walter have retired they have lots of time on their hands. One of their pastimes is entering slot tournaments. They've played throughout the state of Nevada, basically breaking even but having fun, which is all that matters, really.
We caught up with them at the Circus Circus here in Reno and witnessed the following conversation -
(I didn't say that they always got along!)
Nancy: Walter, look!
Walter: Nancy, what is it?
Nancy: Watermelons! They have the watermelons this time!
Walter: Awesome! We always do well on those!
Nancy: I always do, you mean. Remember the last time?
Nancy: I cleaned up!
Walter: I didn't do that badly, either, dear.
Nancy: I seem to recall that somewhat differently, DEAR.
Walter: OK, grab that machine before someone else does!
