I believe the new Ubuntu release this October (12.10) should be called Quixotic Quetzal.
Credit for coming up with it goes to this guy, whose post I saw when I searched for "Questing Quetzal". Since, questing is sort of a sub-set of being quixotic, I'm going with that instead! I think it especially fits because this will not be an LTS and so it will be forgotten like a lost fool soon enough.
They'll probably just go with Quick Quahog.
Quicker Quokka (love this one too)
Queefing Quillpig (rofl)
