Google's humor, or Google being humorous

"kaikai wrote. When ceek visited Google, he wondered if he could use a string of numbers to represent the word Google. So I turned Google over and got a string of numbers 376006, accessed at http://376006.com, and sure enough, it was Google. Is this Google's own idea? Looking at the source code, which turns out to be a simple frame, try the famous http://466453.com which is a domain name jump. So is it Google's humor, or is Google being humoured? "
