Tweed: "To Serve Man" was definitely a Twilight Zone episode.

But, of course, there's the opening narrative of The Outer Limits, which includes "We will control the horizontal. We will control the vertical." (Can anyone remember the entire thing?)

Yet another Star Trek quote: "He called the Enterprise a garbage scow!"

And I can't believe no one has yet submitted this: "Soylent Green is people!!!"
