What does that mean?

Vanity License Plate - RU OK?!

I've seen some pretty funny vanity license plates, some in remarkably poor taste, and a few that I simply couldn't figure out.

This one struck a happy cord with me. Here's how it reads to me:

RU OK?! No, but thanks for asking.
RU OK?! Yes I am, thanks for asking.

See what I mean? Win, win.

Of course it could mean; RU OK?! Because you're driving like a manic.
