This makes me think of a great prank to play on someone. Give a buddy a Christmas card on behalf of a gun store and mail it so his wife finds it. "Thanks for the massive support this last year. Your patronage alone has allowed us to hire additional staff and support our community. We look forward to a great 2014. PS, we took a chance and mailed this to your home address rather than the 'shipping address' you have us use for purchases."
I could see sending a letter to his wife telling her he's cheating, but this is just plain cold blooded.
