Corrected entry: Arthur and Ford find the ultimate question by taking letters at random from a Scrabble set - spelling 'What do you get if you multiply six by nine' - and the words 'Forty' and 'Two' are already on the board. That is five Ys - and there are only two Ys in a Scrabble set.

Correction: They are playing with Arthur's homemade Scrabble set, not a standard one, so he could add as many of each letter as he wanted.
