I rediscovered iTunes U today which is an incredible repository of online University education content for FREE! Videos, lectures, interviews, really cool stuff on a broad range of topics from string theory to ancient literature to anatomy and physiology, but also more rudimentary topics and a lot of K-12 topics too (for you teachers out there!).

I was looking for material about comedy and writing, and found a few related things but I found a great series (only 3 entries so far) called "Funny People" from the 92nd Street Y that has three awesome (and recent!) interviews from three awesome comedians, Steve Martin, Carl Reiner and the late great George Carlin. iTunes U functions within iTunes and it podcast format, so you need iTunes to hear them, but they are totally free and very enlightening to students of comedy.

Find the series here.
