Have you ever seen a sock account that was actually funny?

Since it appears unlikely The Professor is a sock, option 2. Of course the funny socks I have seen didn't post that frequently (since that would wear out the joke rather quickly) and even though many were gimmick accounts they weren't just crude parodies of a straw liberal/conservative, which is probably the worst and least funny type of sock possible.

Why the certainty in ruling out The Professor?  Anyway, Van Der Blubb.

The Professor has an IP from the University of Colorado, which no current posters do, meaning if he has another account it must be one that doesn't post anymore (Aizen?) and thus not really a sock.

Van Der Blubb wasn't a sock either, that was his main and as far as I know only account. He might count as an amusing troll though.
