A dynamite TED talk with one of the best formal rhetorical presentations I've seen.

From TED:

Larry Lessig gets TEDsters to their feet, whooping and whistling, following this elegant presentation of "three stories and an argument." The Net's most adored lawyer brings together John Philip Sousa, celestial copyrights, and the "ASCAP cartel" to build a case for creative freedom. He pins down the key shortcomings of our dusty, pre-digital intellectual property laws, and reveals how bad laws beget bad code. Then, in an homage to cutting-edge artistry, he throws in some of the most hilarious remixes you've ever seen.
