Our new snowclone overlords?
Thanks to my love for the reminder to go a-hunting -- I've meant to track something like this down for ever so long! I don't think I'll ever really understand Bakhtinian analysis, but at least I found the Simpsons quote in context. (Well, that's my level found.)
I'm not so sure about the term "snowclone" yet. I'll buy that "cliche" isn't quite specific enough, and apparently "meme" just makes people wince; but any word that requires an exemplary anecdote to be comprehensible seems unlikely to stand the test of time.
