... I think I've only done 4a. Then again, I might have fallen into one or two more if I were writing more sci-fi.

.. that said, I can think of at least one example in what I read where I absolutely love love love #35. Yes, it's a twee fairy with wings and his name is Toot toot. (Well, not precisely, but you can't know the name or you'd be able to call him up, and you shouldn't!)

Ahem. One of these days I'll hop over and explore TV Tropes. Not enough brain for that right now.
