Do you have a co worker who never stops talking

I once had a coworker who talked constantly. And she spoke so fast that it was often difficult to understand what she was saying. She would jump from subject to subject, and it was as if she never stopped to take a breath so there was never any opportunity to get a word in edgewise. By the time you ever managed to say something, she was already a half-dozen topics down the line.

Really nice person, though.
