In the two-hour pilot for 'Eureka', US Marshal Jack Carter wanted to know about the scientific investigations being conducted by Warren King. When told that King was looking for the "point of origin", Carter asked, "Point of origin for what?"
"Everything," King replied. "Life, the Universe......"
So close. And yet so far.
But even if King had said the phrase in the correct sequence of "Life, the Universe, and Everything", that doesn't mean that he knew of the mission of the Deep Thought computer to compute that very "question".
And it doesn't mean that he knew of 'The Hitch-Hiker's Guide To The Galaxy' as a radio serial, a series of books, a TV series, or a really bad movie. It was just a phrase, and he probably wasn't the first one to have uttered it in Earth Prime-Time's history.
Now if somebody bade goodbye to Marshal Carter as he left 'Eureka' by saying "So long, and thanks for all the fish"........
