A pangram is a sentence that uses every single letter of the alphabet, for example, my favorite: "Jackdaws love my big sphinx of quartz." Coming up with a pangram of any length is quite easy, but using every single letter of the alphabet only once, well, that hasn't been done very often. There's "New job: Fix Mr. Gluck's hazy TV PDQ", or, my favorite: "Mr. TV Quiz Ph.D bags few lynx." After struggling for a few hours, mixing letters and writing the alphabet several times scratching out letters and rearranging them, I finally created a half-way decent one. (It's the only one I came up with so far, but it's IMO halfway decent.) Here it is. "Quartz flock, jinx gym BVDs, phew!" Or, in other words, someone wants a flock of quartz to jinx a certain pair of underwear in the gym, and gets exhausted telling it. If I put a period after "BVDs", then it would be two sentences, so it must be a comma. But, there's a problem here: Nobody calls a bunch of quartz a flock. Sure, there's a flock of birds, a flock of sheep, but a flock of quartz? Is quartz even a singular? It is according to the official Scrabble dictionary, so that's good enough for me.
