I like coming up with ideas for witty bumper stickers. I made this one in light of this article.
Since Cafepress doesn’t appear to allow a seller to have more than one of each kind of item (in this case more than one kind of bumper sticker), this one will be for a limited time only. It’s $4 if you want one. I don’t expect to sell any, but if I do all money earned will go into my son’s college fund. If you are interested, they are available here.
