First come predictions. If someone challenges a prediction and the challenge is accepted, it becomes a bet. It may seem like you have to be some bigwig to take part in a bet, though the rules don't mention anything about it. This is Long Bets, and some of the predictions and bets are fascinating and thought-provoking. And then you have Ted Danson betting that the Red Sox will win the World Series before the US men's soccer team wins the World Cup (I think he's right).
I'm thinking of challenging this one: "Brooke Shields will be be a recipeint of the Kennedy Center Honors for her lifetime contributions to American culture through the performing arts, within the next fifteen years."
