Waving to Aliens

There was a brief article in the Sunday Sun today about the "proper conversation starter when greeting an alien (from outer space.)" I only have one observation in this regard - the rabbit doesn't wave to the fox! Some of us remember the Twilight Zone episode - To Serve Man. If you don't,, check out http://en.wikipedia.org/wiki/To_Serve_Man_(The_Twilight_Zone)
