I don't see the point of restriction to magnitude one. And if you do want that, it's much easier to just specify the phase angle.

True, but it obscures the imaginary vs. real distinction.

Also, this is a joke. I think.

I demand my jokes to be totally rigorous!

Yeah, it's a joke, but it could also be a cute (and hence possibly mnemonic) classification scheme.

Fair enough. :) I do find when I hear a science related joke that I take about a minute to determine whether it's "correct," then laugh.

Best one I've ever heard (only works if you've taken a complex algebra course):

What's the contour integral around Western Europe?

Zero - all the Poles are in Eastern Europe.

All jokes about quantum mechanics are automatically unfunny.

Actually, there are Poles in Western Europe, but they're removable. ;)

(potentially offensive) So you can mathematically prove that Hitler destabilized Europe?

*searches Internet for removable poles*

Ha!

Edit: By the way - and I fully grant this may be obvious - "removable poles" is not a very good search term.

A plane is flying from Warsaw to Paris. The pilot announces that they are passing over Rotterdam, and the world's largest container ship is visible out of the windows on the right side. Shortly afterward, the plane went into a tailspin and crashed.

A later analysis revealed that the crash occurred because all the Poles had moved into the right half-plane.
