Looking for two SDMB posters with cool signatures

[Schnitte]

Somewhere among the Teeming Millions are two registered users with signatures citations I really like:

"Of course", my grandfather said, stepping out of the time machine, "there is no paradox if I shoot YOU!"

and

The only thing a nonconformist hates more than a conformist is a nonconformist who fails to conform to the accepted standards of nonconformisms.

Who did say that originally

Some of the mods are apparently in a real (http://boards.straightdope.com/sdmb/showthread.php?threadid=101602) bad mood (http://boards.straightdope.com/sdmb/showthread.php?threadid=101983) 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.
