"Bush, Clinton, Bush, Clinton"

Apparently Bill Clinton and George Bush Sr. have become quite good friends.

"That's a good relationship. It's a fun relationship to watch," [George W.] Bush said in an interview with CBS News broadcast on Sunday.

While attending Pope John Paul's funeral, Bush said, "It was fun to see the interplay between dad and Clinton. One of these days, I'll be a member of the ex-president's club. ... I'll be looking for something to do."

He said ex-presidents share rare experiences that others cannot understand. "And so I can understand why ex-presidents are able to put aside old differences," he said.
