Man am I glad that's not the real etymology of husband. It's actually from the Norse for "master of a house."
Also, here's the verb form of husband according to Websters:
"To direct and manage with frugality; to use or employ to good purpose and the best advantage; to spend, apply, or use, with economy."
It would seem to suggest that it is the husband's job to improve "the cave" with purchases such as new Axioms. After all they are a (comparatively) economic purchase intended to bring about the "best advantage." Maybe that's the best approach when questioned by the wife....tell her to look up the word "husband" in the dictionary while you go buy stuff...
Something tells me you might come home to find the locks have been changed.
