"Slenderize Exactly Where You Want!!" This "Hot" item is on our Wonder Weird list of products we wish were still around. Just imagine, you don't need to diet, work out, or watch what you eat. All you have to do is slip on a pair of these great looking pants, inflate them, and let the fat melt away!!! Well, of course this was the idea behind "Wonder Sauna Hot Pants" and of course, it never worked. Technically, you would lose some weight, but if you drank a glass of water, you would gain it all back. At least you would look really cool wearing pants that were really hot!
