Colorado entrepreneur David Baron has entered the fray, arming the perturbed "seat harpies" with a new and humorous weapon.
"The concept is a bit like refrigerator magnets, only for your toilet," Baron says. Named Bowl Busters, the stickers are designed to be placed on the toilet itself -- typically under the lid or the seat -- though they work as well on walls and mirrors, since they are easily repositioned or removed. This link shows a few of the designs available as puffy stickers: reminders to lower the lid, practice careful aim, and so on.
This is an ill wind a-blowin', fellas -- although, to fight back, we could always just not use the bowl at all. Of course, that would amount to Turd Terrorism, and is in no way condoned by the editors and members of this website, nor by this author.
