On the positive side: The dog was under anesthesia. On the negative side: It was a tattoo of a cat, and not just any cat -- Hello Kitty.
(From the anti-Hello Kitty blog, Hello Kitty Hell, found via Metafilter.)
(And take the Hello Kitty test, which is cute and which told me people must think I'm self-centered and evil.)
UPDATE 2014: Hello Kitty is not a cat!
