The Answer: Most of this firm's 70,000 seasonal white-collar employees work only four months a year.

The Question: What is H&R Block? -- The response that terminated the reign of Jeopardy darling Ken Jennings.

It was yesterday afternoon that word hit -- and while the blogs had suspected as much for awhile -- we soon learned the rumors were true: America's favorite know-it-all, the greatest game-show winner of all time, had met his match. Searches on "Ken Jennings" skyrocketed 318% on the news. Even "Ken Jeopardy" jumped in search, suggesting the perfect name change for the recordholder. Jeopardy-watchers went hunting for H&R Block (+132%) (the correct answer), FedEx (+194%) (the incorrect answer), and Nancy Zerg (who dethroned the ruler). The moment Jennings gave that sly, sideways smile, we knew he was sunk. In the weeks before, we'd seen gloomy searches on "Ken Jennings loses" and "Ken Jennings lost." Why never a "Ken Jennings winner"? Yes, the 74-game run is over, but the elfin wunderkind walked away with more than $2.5 million. Despite the loss, TV viewers weren't rid of him -- he popped up again later that night on David Letterman (reminding us of his touted Top 10 showing) and on Regis and Kelly on Wednesday morning. And Jennings junkies can always visit him at his own site, Ten Favorite Films by Year.
