Joke of the week.

I think Fareed Zakaria GPS is one of the most educational and insightful news show on TV today. Anyone interested in the goings on outside of the United States should read his book and TIVO the show. That out of the way, nothing is perfect. One of his guests this weekend was Columbia University J School Dean Sree Sreenivasan who graced us with this brilliant exchange.

ZAKARIA: Sree, what strikes you about this? I mean, what I'm struck by is how -- the fact that you don't have that much coming out of television has meant that news organizations like CNN have to rely on people on the street, iReports, Twitter. SREE SREENIVASAN, PROFESSOR, COLUMBIA UNIVERSITY JOURNALISM SCHOOL: Right. And it's causing a lot of consternation within newsrooms, because they're not used to putting things on the air that they cannot verify 100 percent, or as close to that as possible.

The uselessness of the Ivy never ceases to amaze. Only 100 percent verifiable on air. Right. Clown.
