Here's the best way to smuggle in that new Carvin. Go to Victoria's Secret, buy something cheap but cool, and have them put it in a Victoria's Secret box. Then as you come in the door and you wife sees the box, you say, "Hey - no peaking. This is a present for you later." Then take the box into your music room, remove the Carvin, and you're set!
