I recently watched this movie called The Hitchhiker's Guide to the Galaxy and although most of it is quite silly there were some gems in the beginning and the end. The movie starts with a civilization reset, the earth is blown up and only two humans escape, one with his alien friend and another with the president of the universe. When they meet in space the president of the universe show them this clip about 42, the answer to life and everything.
Although the author of the original book says:
"The answer to this is very simple. It was a joke. It had to be a number, an ordinary, smallish number, and I chose that one. Binary representations, base thirteen, Tibetan monks are all complete nonsense. I sat at my desk, stared into the garden and thought '42 will do' I typed it out. End of story."
-Douglas Adams
I’m sure it was a random number…
