That's GP's point -- their answer is a joke, taking the piss out of the questioner by providing the standard fatuous reply.
A great tactic if you don't want the job.
Also if the interviewer is a naive, cultureless soon-to-be corporate tech drone, fresh from the saccharine bleatings of their politically correct and sex-less, drug-less university days, with no concept of sarcasm, or human complexity, or of what a hideously self-important and embarrassing answer it is.
Completely agree. I also think, "disingenuous" since it's the most obvious fake answer, and also "uncreative" since they couldn't come up with anything better.
