President Barack Obama was seen impatiently waiting for former President Bill Clinton — not one to be on time — on Air Force One at Ben Gurion Airport in Tel Aviv after attending the funeral of former Israeli President Shimon Peres.

When we have two egos as large as these two men do; we have to wonder, is the dog wagging the tail or is the tail wagging the dog???
It is surprising to me how they have united in ARMS ever since BB went public that she was running for The Big Chair. Prior to that and possibly still so, these guys hated one another.
I have to think that Wild Bill is making a statement by making the sitting president dance to his tune. Some people call it signifying.
Just an opinion.
The Goomba Gazette 
It’s like when you were single and out with the guys, at the local hamburger establishment. One of your friends strikes up a conversation with someone as all the guys are getting into the car. The friend keeps talking and talking. He knows everyone is ready and wants to head off chasing skirt, but he keeps on talking and talking. Finally you get tired of waiting and shout, “Let’s Go!”.
Same thing on a different level, Air Force One.
