The Social Network
Facebook was a website made by some douche who took the idea from guys, and cheated his friend out of money. Or was it just a string of events that occurred in such a way that the protagonist was made out as the villain? Either way, it's a movie based on one of the most popular websites around. That could easily provide some jokes. But some of the events in the movie could also make for some good notes. I think it'd work well for a Riff.
