I haven't watched South Park in a long time, but at the college where I work, one of the instructors really admires the writing in episodes of South Park. He sometimes refers to particular episodes to illustrate ideas in class. This got me into watching the series again (can't believe they're on season 11 now).
I also came across a website that lets you create your own South Park characters. They just recently updated to version 2.1 and added a whole bunch of new clothing and props. You can kill a whole afternoon in your office by using it to create South Park versions of your co-workers. It's eerie how close you can get sometimes.
