A few months back W & I were sitting in a Panera and I said, "Wayne, what would you do if a giant beaver walked into the Panera, ordered a coffee, and sat down at a table?"
He responded with raised eyebrows and a confused laugh and a shrug and a look that said, "Suzanne, you are so special to me in so many inexplicable ways."
I responded by drawing a picture of the beaver on a card so he could more easily understand what's going on in my brain. Communication is such an important part of a good marriage, folks.
That, and acceptance and tolerance of your spouse's odd imagination.
