I remember a high school science class I took. We were studying radio and television transmissions and the teacher pointed out that a television signal doesn't ever really die, and that way out in space were the remnants of the first television broadcasts.
And of course, he pointed out the remote possibility that some far-off intelligent civilization's first contact with our human race could very well be an episode of "I Love Lucy", which might have explained why there was no contact from any other intelligent life-forms to that point.
But really, that wouldn't be so bad, would it, I mean, when you consider the kind of crap that's floating through the air these days? Imagine ET sitting through an episode of "Jackass" or "Survivor", and then wonder how there hasn't been an interstellar war.
But suppose we had something to say about it. Maybe through the magic of the Internets or something, we could devise a way to selectively provide our best first-impression to some distant civilization, and that task fell to you?
What part of human existence, past or present, would you offer to the Extraterrestrials as our "best foot forward"?
Be careful now, "The Three Stooges" are probably floating past Alpha Centauri as we speak.
