This is hilarious though am not sure if it fits into the Google Easter eggs category:

google homepage
Sorry, Google does not serve more than 1000 results for any query. (You asked for results starting from 990.)

In case you didn’t notice the flaw, that second (or first) ‘o’ dropped out of ‘Google’.

To reproduce this Google bug on your machine, search anything on Google and then append "&num=100&start=990" to the Google URL without quotes.

For instance, if you search for "pajamas media", then your Google URL would look like:

Original: http://www.google.com/search?q=pajamas+media

Modified: http://www.google.com/search?q=pajamas+media&num=100&start=990

Some CSS guru may help you figure out the reason behind this but the hack was initially discovered by Brian Brown at SEOmoz.org.
