My sister teaches English and asked her pupils (or "learners" as we are now required to say in disgusting PC-ese) to discuss how Shakespeare uses nakedness as a metaphor in Macbeth. You know... "and pity, like a naked new-born babe" and all that.

Well, one replied with words to the effect that there were "nude babes" in the play. Somehow the fact that that comment is so funny seems to go to the heart of the naked/nude debate.
