Did you know that the word UNCOPYRIGHTABLE* is the longest word in the English language (at 15 letters) that doesn't repeat any letters? Is it even a word? You don't hear it much in conversation. Well, too bad. I say it is, and so I copyright it.

No, I'm just kidding. It's uncopyrightable.

If you like things in which letters are not repeated, you may also be interested in the following 26 letter pangrams:
Mr. Jock, TV quiz Ph.D., bags few lynx.
Blowzy night-frumps vex'd Jack Q.
There's also one with the word Vox right in it, but it contains the Welsh word crwth and the clearly made up word Squdgy. Also, jimp, fez, and blank. I'll let you put them in any order you want. It don't make no sense to me.

I guess there are probably a few other ones out there, but I can assure you they're not as good.
But then, I repeat myself.

* Yeah, right, like I'm really going to count DERMATOGLYPHICS
