The quick brown fox jumps over the lazy dog.

     "The quick brown fox jumps over the lazy dog" is a famous quotation that sounds silly, until you find out why it is so famous. It uses every letter of the alphabet at least once--so when someone was learning to set type, years ago, or wanted to test a typewriter with a key for each letter, he or she only had to type that sentence. It was useful when learning to type, as well. It may still be useful to people who want to check on code they have written for new fonts. Or, you might try texting it.
