Joltin’ Joe commits a gaffe, and Dirty Harry plays right along.

At a campaign stop in Las Vegas, Joe Biden asked people in the crowd how many of them know someone who has served in … Iran?

While most of us would have sat there in stunned silence, Harry Reid can be seen in the background raising his hand like a schoolboy dying to give the teacher an answer.

And guess what happens next … Joe asks another question – How many know someone who has been injured or lost in Iraq or Iran?  And Reid raises his hand again!

I wasn’t aware that we had any troops on the ground in Iran.  Thanks for the history lesson, Joe!

Watch these two Mensa candidates in action…
