There used to be an old joke about a lion that roared and demanded "Who is king of the jungle?" from every passing animal. One day an elephant ambled by, "Who is the king of the jungle?" the lion demanded ---- the elephant picked the lion up with his trunk and flung him against a tree, once, twice, three times.
As the lion limped away, he looked back over his shoulder and said, "You don't have to get violent just because you don't know the answer!"
So yesterday at the daily press briefing in the White House, Jay Carney, unable to declare whether Tel Aviv or Jerusalem was the recognized capitol of Israel -- tried roaring and laughing at the question when he didn't know the answer.
