@Japanese Ghost You could secretly order it, and not tell your wife. When you get in the mail, you could display it when your wife is not around. If she happens to find it, you can say you found it lying in the road somewhere, and she will be none the wiser:)
@Nathaniel7, except that she saw this post already!
@Nathaniel7, I don't know if I am comfortable with you saying "Sheldon Sack" Just don't add an s at the end of Sheldon ;-)
@Japanese Ghost well maybe she needs to accept that you have hobbies and deserve , nay need a Sheldon sack doll:)
