Keswick's Hologram was a hologram made by Keswick so that he could get more work done, but it only appeared in Toast of T.U.F.F.. A running gag in this episode was someone (usually the Chief, Kitty, or Dudley) talking to the hologram believing it was Keswick, and then seeing the real Keswick (who played a joke on them) somewhere else saying, "Actually, I'm over here." and waving.
Near the end of the episode, his hologram was "vaporized" by R.I.T.A. who believed it was him. It has not been seen since.
