Got rejected by Google? Don't worry, you don't want to work at Google anyway. Here are two of my favorites, and you can read the rest here.
Everyone is awesome, so they can hire the very best people to do even the most mundane jobs.
"The worst part of working at Google, for many people, is that they're overqualified for their job. Google has a very high hiring bar due to the strength of the brand name, the pay & perks, and the very positive work culture. As a result, they have their pick of bright candidates, even for the most low-level roles."
"There are students from top 10 colleges who are providing tech support for Google's ads products, or manually taking down flagged content from YouTube, or writing basic code to A|B test the color of a button on a site."
Google staff are so outstanding that there's an internal joke about it.
"... I used to joke with my colleagues that Larry & Sergey go out on their yachts - tie them together, sit back on the same recliners you'll find on their jumbo jet, each on his own yacht/set of yachts, smoke cigars, and put up pictures of Googlers with little snippets like "was a GM at muti-national telecomm company, got a Harvard MBA and is now answering Orkut tickets." and then they would erupt in laughter and clink their cigars & Scotch together in celebration. This, of course, is highly unlikely given neither of them would ever smoke a cigar or drink Scotch. Remainder is plausible."
