Joe Biden's Dan Quayle moment

Of course if Dan Quayle had done this it would have been headlines for days. But Biden does it and gets a pass.

Democratic vice presidential candidate Joe Biden found himself in an embarrassing situation during a Missouri campaign appearance Tuesday.

During a stop in Columbia, Mo., Biden was speaking before a large crowd when he decided to give special recognition to State Senator Chuck Graham.

"Chuck, stand up, let the people see you," Biden shouted.

However, Biden did not realize that Graham is confined to a wheelchair.

"Oh, God love you. What am I talking about? I'll tell you what, you're making everybody else stand up, old pal. I'll tell you what, everybody else stand up for Chuck. Stand up for Chuck!" Biden said.
