I can tie a tie in one second. I use a trick taught by a magician known as the Amazing Randi and appeared in the now defunct OMNI magazine of the late '70's. It's way cool & you only need one hand! I often flip the tie over my shoulder as I'm tying it so others can't see the knot. Then I ask them to count while I "tie" the tie. I whip it out in an instant, already tied. I'm sure you can find this method somewhere on the web. I don't have time right now to make a video of it or describe the method... maybe later.
