If you're really against smoking them or keeping them for guests (LOVE the term mooch-idor, by the way) and you don't mind a small white lie, then go buy some sticks that you do like to smoke and that appear similar to the cigars your wife gave you and donate the Gurkhas to CfW. That's just another option. Personally, it's not an option I would take because it involves lying to my wife and I want to encourage her to continue to support my hobby.
I'm in the "thank her profusely and keep them" camp - if nothing else, they'll probably be fantastic yard-gars for you in the Spring.
