Reiner's Message: Hillary Rocks!

Love or hate Hollywood endorsements, at least Rob Reiner's backing of presidential candidate Sen. Hillary Clinton has humor.

The "Meathead" of All in the Family stars in a funny new online video in his real-life job: as director.

You'll see some geeky volunteers mildly campaigning for Clinton when Reiner steps in to push for passion.

It works, of course. Now if he could give the candidate a little lesson in enthusiasm.
