Olperfesser

From Wiki Gonzalez

Olperfesser, or OlP as we like to call him, is apparently old, and a professor. There's no proof of either of these. What we do know is that he's a big Red Sox fan who feels that Dan Duquette got the shaft.

He was a prominent poster to Old Primer, usually in the Sox Therapy section, but disappeared after registration was instituted. Even before then, he tended to vanish for long stretches of time, which lends credence to the rumors that he is magical.
