[Someone refresh my memory: Was this example supplied by Okrand?]
[Update, 11/24: Marc Okrand confirms via email that he indeed is the source of the Klingon line. He explains that peDtaH 'ej chIS qo' means "It's snowing and the world is white." Okrand is thanked in the liner notes (with the Klingon expression of gratitude, qatlho').]
