George Washington had one. So does your printer. "Queue" can refer to either a braid of hair hanging down a person's back, or a line of people, print jobs or anything else. It comes from the Latin word coda, which means tail.
In Scrabble, "queue" earns a minimum score of 14, nothing to sneer at. Even better, it clears your rack of a bunch of awkward vowels. And, of course, you lose the "q," a letter you don't want to be saddled with at the game's end.
