There's a tradition of skullduggery-related names: Guile, Gambit, Gauche, Heist, Larceny (with variants Petit Larceny and Common Larceny), Racket, and Stalin (it optimizes your code -- brutally). "Chicken" is I believe related to an actual rubber chicken (which of course is also unreal).

And the obvious one: Scheme(r).

John knows already, but the Scheme were meant to be called Schemer, but the file system only had 6 characters in the filenames.

Apropos, the suffix "bit" is popular too: rabbit, orbit, gambit, picbit, twobit
