From the witty Jon @ silicon.com:

The latest game to sweep the web is called Googlewhacking.

The game involves searching Google's massive two-billion page database for two words that return a "Results 1 out of 1" message at the top of the page.

However, a Googlewhack doesn't remain one for long because players post the link on the game's website ensuring that it will consequently return two results.

All entries, or Googlefactors, must be verified via the dictionary.com website.

The Round-Up has better things to do than waste time playing silly games but for the record "portakabin monkey" got 30 hits, "Cheddar homunculus" got 10, while "slimy sandpaper" got a disappointing 712 - so it's not as easy as it sounds.

(If you play this game with your colleagues you get a fascinating, if occasionally frightening, insight into how their minds work. The silicon.com reporter who shouted: "I can't believe liquorice flagellation returns 29 results" is now being given a wide berth in the newsroom.)

Research team - go!
