I think the universal translator must be down. What's "unriffed"?
Yeah what Sigs said. "Unriffed" just means watching a movie like you would regularly. Some movies are only bearable if riffed (see Manos the Hands of Fate). Riffing is yelling at the screen, making fun of the movie/short, made popular by MST3K. Here's a short example, which is probably my favorite Short.
I think they estimate about 600-700 jokes per episode
Joel was brilliant. He took something we all did when watching films with friends, and turned it into a product
And Joel's such a "sleepy" mellow guy. You'd think someone like Bobcat Goldwaith or Gilbert Godfried would invent yelling at a film. But that's why it worked too, Joel doesn't use any annoying "shtick" like those two.
