I'm watching the classic "To Serve Man" on the Twilight zone Marathon. At the end the victim is fed sandwiches wrapped not in zip lock,oh no,but the far advanced saucer builders prefer the old tear sheet plastic wrap. You can forget Styrofoam containers.the super advanced beings prefer those old fashioned metal picnic plates. They make a nice ringing sound when thrown to the ground dramatically.
Its so hard to imagine 50 years in the future huh?
