Or, you could do like my (now deceased) brother in law and have a friend call the house and ask for "Ken". The wife says, "Ken is not here, he went to the gun club". The friend then says "I just wanted to congratulate him on winning the raffle for the xxxxx rifle at the club. "Ken" walks into the house a bit later and the wife is all excited for him and asks to see his new rifle. As far as I know, the wife never found out about "the sting". Another thing that you can do (also only works once) is to wrap up the new gun and mix it in with other presents under the tree marked "To: John From: Santa. Eventually, that present will be handed out (with no one knowing what it is) to be opened. When opened, the proud owner says "Look dear, Santa wanted me to have this new Baretta (or whatever) pistol! Then you will get "the look" with "ok, you got away with that this time but don't try it again" muttered under her breath. Sometimes you just have to be creative!
