Rufus Q Shupilluliumash used Google to look up information on RD during the long flight from Alpharalpha B to Amana XI after he had finished viewing pornography. Feeling lucky, he hit the "I'm Feeling Lucky" button and found information on Research and Development. This was not pertinent to his case and it taught him not to use the button.
How Rufus was able to use Google in deep space is known only to the Omniscient Narrator.
Rufus later used Google to look up Royal Drive. Google produced no hits, from which Rufus concluded that Royal Drive was unauthorized (after satisfying himself that he was not using the Chinese version of the search engine).
