Rhett and Link's T-Shirt War

Not saying these guys are actually clowns, but there are a lot of great clown ideas here, and really well executed use of stop motion.  The gag of pulling real stuff out of the shirt or vice versa is really well used.  Almost an object lesson in one-upsmanship and clowning, but in a film form that would be a little harder to pull off on stage.    And their marketing of the shirts afterward is great too.

A couple of these effects have me thinking...

You can find out more about these guys at their website: http://rhettandlink.com/

I'm definitely planning on taking a look at the rest of their pieces, based on this one.
