That's extremely funny, but I'm almost completely certain that's not as "vanilla" as you think it is. Perhaps it was enabled on the command line? It looks like

  defaults write com.apple.finder QuitMenuItem -bool YES

will do the trick. So perhaps you're operating from a custom com.apple.finder preferences file.

Yes you are right. I have absolutely no recollection of tweaking this, but it seems it has been done. (I just checked a different, definitely unadulterated 10.3.x install, and it doesn't have the Finder quit menu item.) Thanks for correcting me.
