This funny Birthday Greeting card from NobleWorks might just start some minds turning as to other ways to save on the expenses of their children. Actually Doris and Bill's idea of saving on their children's air fares isn't too shabby. When you think about it, they are snapped in so they can't get out and rummage around the luggage area. And since they are in separate cases they won't be able to fight with each other and disturb the passengers. So as long as you make sure they are able to get enough fresh air what can it really hurt? After all, you now have to pay more for any luggage so the airlines will still make some money...
