My co-worker Rainer sent me this gem:
Many typists know “The quick brown fox jumps over a lazy dog” as a
thirty-three-letter sentence that employs every letter in the alphabet at
least once. Now fix your eyes on a sampling of the best pangrams of even
fewer letters. What you are about to see are meaningful sentences that
avoid obscure words yet contain every letter of the alphabet:
Pack my box with five dozen liquor jugs.
That’s all he sent (Rainer knows me), although the blurb suggested there were
other examples. So I did a quick Google Search and found this. There were a few examples with even fewer letters, but none of them were anything I could ever imagine myself saying.
