I laughed out loud when I read this........

Well there is a website politifact.com and it has these truth-o-meters. Kinda like the believe-o-meter. and they have true, mostly true, half true, barely true, false, and pants on fire(that is for the completely false you didn't even think before you spoke kinda false). Oh I forgot to mention that the site compares all the candidates and how truthful their statements are. And the one below was the funniest one not because they refute what the Senator said but the way they explain why he is a pants on fire.
edit- I forgot the headline.

"The president is brain-dead."

Joe Biden on Wednesday, July 4th, 2007 in Des Moines, Iowa.

Irresponsible claim (and wrong medical diagnosis)

During a campaign stop in Iowa on July 4, the six-term senator declared, “This guy is brain-dead.”

It’s an extreme charge, since brain death is defined as “irreversible unconciousness with complete loss of brain function” (Encyclopedia of Death and Dying).

Needless to say, we find the charge ridiculous. There’s no evidence Biden performed the necessary medical tests to make such a diagnosis. We would have accepted the results of a cerebral blood flow study or proof that Biden had examined Bush to see if he had an oculocephalic reflex.

Indeed, even people who disagree with the president about Iraq and assorted other issues will acknowledge that the president has spontaneous respiration and is responding to stimuli.
