This is my HUSBAND'S..not mine, but..a (LARGE) box containing 50+ empty 7-Up cans that came out in the 70's. When you stack them just right they make a picture of Uncle Sam (I think). DH just will not give those things up. He thinks they're collectible. So SELL the damn things!!
My DH has a beaver skull. It lived on my kitchen counter for almost a year until I made him relocate it outside on the porch.
