Heard in a bookstore
Bookseller #1: So who is this "Anonymous" person who keeps writing books?
Bookseller #2: K., "anonymous" means you don't know who wrote the book.
Bookseller #1: Yeah, but, A., it must be someone, right? I mean, I keep seeing books written by "Anonymous" all over the store. The guy must be a genius or something.

(yes, bookseller #1 did say that sentence)

You have to love chain bookstore employees ...
