You're traveling to another dimension. A dimension not only of sight and sound but of mind. A journey into a wondrous land whose boundaries are of imagination. That's a sign post up ahead. Your next stop ...
Take one Mr. John Doe. It's January 1, 2005, and he's wasting away his time watching his tv set. He randomly selects a channel on which a black and white show from the early 1960s depicts a group of humans at a bus stop cafe.
Someone informs the group that a UFO was seen landing nearby. And a head count of the people in the cafe reveals that there is one more than should be there. So, they begin to try to figure out, unsuccessfully, who is the non-earthling.
Eventually, everyone leaves except the cafe clerk. But, after a commercial break one of the passengers returns to calmly tell the cafe clerk how everyone else who was just in that room is now dead due to a collapsed bridge down the road.
Well then, how is it that the one passenger survived unscathed? Simple. He's a Martian. And he proceeds to stir his coffee cup with a third hand that neatly protrudes from within his coat providing convincing evidence that he is, in fact, from Mars.
You see, he's a scout visiting Earth to gauge its suitability as a Martian colony. Earth is suitable, and the main invasion force on its way.
Not so fast. The cafe clerk politely but firmly advises him that his plans have been thwarted. For you see, the clerk is from Venus, and his planet also has plans to colonize Earth. The Martian invasion force has already been annihilated.
The cafe clerk removes his hat to expose a third eye planted squarely in his forehead as convincing evidence that he is, in fact, from Venus.
Mr. John Doe has been watching an episode of The Twilight Zone. And, he promptly thumbs the remote to see what's on another channel.
