awkward pedagogical metaphors

So i love my comp-ling teacher, and today was good for a laugh. We were talking about manipulating lists recursively in prolog, which involves repeatedly removing the first element and "putting" it somewhere else. To try to clarify, he said that we want to get to the green center of an onion, and that we are going to be peeling off layers. He got to the part of the explanation where that part of the recursion was done, and said "ok, and now we fry the center of the onion, and start putting all those layers back on!" and traced how the layers get "put" back on in the third argument.

When that part of class was over, i thought "hmm, so we have an onion with a fried center... this does not sound appetizing. I do not feel as though we have accomplished much..."

:D

just thought i'd share
