not exactly spoonerism

So Dad was trying to say that we needed to run the dishwasher because we had "no more bowls", but he kept tripping over the "no" and turning into "nor," and eventually he came up with something that sounded like "normal boars."

Mom: We don't have any extraordinary ones, just normal.
Dad: Nor-- Nor mo'-- We're all out!
Me: Of normal boars?

... it was funny at the time.
