McCain’s ‘Dean Scream’?

It seems to me that John McCain’s “bomb bomb bomb bomb bomb Iran” outburst is his very own “Dean Scream,” if you know what I mean:

Is someone who is this cavalier about going to war really fit to be President? After his musical interlude, McCain declared that, after all, Israel is being threatened, and we can’t allow that. Not very convincing — and really kinda weird.
