'Drawings found in atomic fall out shelter on Jikthroom Beta'. Wonder what they needed the fall out shelter for...
Jikthroom Beta was a planet which contained a fallout shelter, inside which were drawings of the super-computer Deep Thought, the number forty-two, and other scribbles related to the Ultimate Question of Life, The Universe and Everything. It could be the planet where Deep Thought was built, although this is merely speculation.
Appearances[]
This planet and fallout shelter were only mentioned in the television series, at the beginning of Episode 5.
Forty-two! Is that all you've got to show for seven and a half million years' work?
Is that a mouse?
