Some of the mods are apparently in a real bad mood lately so you may want to ask if this can be moved to IMHO before they descend.

Actually, I’m going to leave it here for now. Despite the thread title, I read the question to be “who said these things first,” and that the thread title is to attract the people who had the quotes in their sig, on the theory that they might know.

I might change the thread title, though.

And I may move it later, if my guess is wrong.
