Maltz said he once heard about a non-Klingon who reported that Klingons said "Tuesday" when expressing their wish that something turn out well. He said the writer of that report misunderstood. The expression is indeed povjaj, but it means "may it be excellent" and only coincidentally is it homophonous (my word, not Maltz's) with the word for Tuesday."
