Well,
Zort is one of Pinky's many exclamations (along with "Narf", "Poit", "Zounds", "Egads" and others) and
Zork was a classic text-based adventure game lovingly referenced in roguelikes such as nethack (Ever wonder why the currency of the Dungeons of Doom is 'zorkmids'?)
Kind of a pun, I guess. Not a very good one though.
(I just love that you can plug "Zort" into the wikipedia and get redirected to PatB!)
