Ta, modgod, for the greetings (and for all your heavenly, irreverent posts).

I would love it if you would elaborate on this....I thought it was funnier because of the pupil ("learner" indeed! some pupils resist learning, doesn't they?) not realising that "babe" meant "baby" in this context....not because of the nude/naked dichotomy. [questioning/confused-e]

You are quite right about the "babe" thing. But it seems also to point out the difference between nakedness, which is a clinical fact, and nudity, which has connotations of sensuality. The fact that said learner instinctively switched to "nude" when he thought of babes kind of says it all. Or maybe not. Maybe I just wanted an excuse to tell my funny story.

Anyway I would suggest that a big majority of people would refer to a "naked" baby but a "nude" pin-up.
