Punderful, but blunderful

Yes, "towed" and "toad" are homophones, which means that a sign reading "Witches' Parking Only/All Others Will Be Toad" is kind of amusing when hung on the wall of a garage or something like that. (Actually, it would be really amusing if it were attached to a galvanized steel post and placed near a curb, but the city public works department might not feel the same way.)

What is absolutely not amusing, because it's completely out of place and makes absolutely no sense in this location, is a bumper sticker reading "Witches' Parking Only/All Others Will Be Toad" on the rear bumper of a car. I would have complained to the driver, but I was afraid she would turn me into a newt.
