They are a fungus upon the land.
Masked Mom's One-Word Review: Fungal.
(Exceptions can be made for people with children under, say, seven in their lives. Everyone else--cut it out!!!! I mean seriously--I've seen yards with 18 or 20 of the damn things. Wouldn't it be way more time, energy and cost efficient to just put a big billboard up that says, "I have way too much money and way too few brains." Shoot, we can do it in neon if it'll make 'em feel better.)
