Stupid Vulcans.
OK, so, if you're as much of a nerd as I am/was/whatever, you might know the Vulcan greeting "Peace and long life," which elicits the response "Live long and prosper." OK, now, I know that peace and prosperity aren't the same thing. But wouldn't it be more efficient for one of them to say "Same to you" or something like that? Doesn't anyone else think that efficiency is logical?
