I suppose if you are going to show a task live on television, you have to make the reward or penalty more meaningful than last years tasks.

However, I think it shows the producers are getting a bit twitchy about the success of the show.

They're worried that Big Brother is going to be overshadowed by the World Cup, or just won't be as good as last year, so are coming up with gimmicks like this and the surprise eviction.
