Gee, it's a good thing they haven't needed to refurbish the Darth Vader or Kermit-the-Frog statues.
(In fairness, such statues are "grotesques," or artistic waterspouts, used artistically to represent scaring away evil spirits. They are such objects, which, when used as drainspouts, are called "gargoyles." "Groteque" comes from "grotto," meaning "cave," whereas "gargoyle" comes from gargulio, meaning "throat," or "gullet.")
I found it a neat experience to visit a Gothic cathedral with central heat and air. Last time I went to the National Cathedral was almost 10 years, ago, I guess - I went to a Christmas concert when I was visiting my parents.
