A few weeks ago we showed you a preview from an episode of the mtvU web series Stand-In wherein Matt Stone and Trey Parker surprised an NYU writing class. Well, the full episode debuted this week, and it is great. In just six minutes, they deliver more useful advice about telling stories than you'd get from an entire semester in most undergrad classes. So, watching this basically saves you several hundred dollars. Try not to spend it all on booze.

For more with Matt and Trey, don't miss The Making of South Park: 6 Days to Air when it premieres Sunday at 10/9c. Meanwhile, new episodes of South Park return tonight at 10/9c followed by the season premiere of Nick Swardson's Pretend Time.
