Though it has ceased recently, there was a period of time where almost any gimmick that came along would either be attributed to myself or Kinetic (sometimes Banky, too). For the record, here's every gimmick I recall creating:
David Schwimmer (the gimmick from early 2003, not to be confused with the sn I recently used)
Whiskers
The Ghost of Kurt Cobain
Incandenza (1978-2002) (never got off the ground after Jingus—when he was a mod—threatened to ban anyone who faked their own death)
Tyrone Slothrop (also happened to be the legit screenname I used for the handful of times I posted when this place was at ezboard)
Officer Schmidt
Scott Keith (fairly certain I was TSM's first Keith impersonator)
There's more that I don't remember right now. I had something like ten different accounts at one point.
