The idea came to me while read the "Googladiator" thread.
Try a one or two word search on Google. The next poster needs to find a one or two word search with fewer results. No "zero" results allowed.
Also, it would be very easy to get down to double digits but try to move slowly, I think it'd be more fun. It's kind of like Google fight but in reverse, I guess.
The result number changes from day to day (and sometimes from country to country) so I don't think there's much use to check previous results. Besides, you will only be cheating yourself!
So, let's start with a nice, big number:
"see" - 2,390,000,000 results
edit: In order to forcefully slow down the game, I propose that until we get below 100 results or so, each poster needs to find a search with a least 90% of the results from the previous poster (i.e. next poster needs to find something with at least 2,151,000,000 results).
TaintedDeity: The trick to being a good poster is in the posts you don't make, not the posts you do make. Or something.
