Fun With Google
A couple more fun thing for you (in case the earlier ones didn't kill off your day already).
One is a game where, based on the results displayed, you have to guess the Google search terms. It's pretty tough if you're not familiar with some of Google's advanced search methods.
Another game where you see a land mass from Google Maps and you have to guess where in the world it is. Tough game, but made easier (slightly) if you drag the map around a bit to look for a noticable geographic element.
And speaking of Google, if you're sick of doing searches where affiliate and price comparison links (like shopping.com, bizrate.com, ebay, etc...) clog up the first several pages of results (especially the case when you're searching for a specific item number or part), Give Me Back My Google will eliminate some of that mess for you.
