A phrase used to segue to a refutation (usually an embarrassing video) of a claim made by an individual on The Daily Show with Jon Stewart. Began with his interview of Kramer from Mad Money, where Jon got angry and rather than say anything challenging Kramer's words, simply shouted, "Roll 212!" which was a video of Kramer describing sketchy business practices he had done.
Guest: "I don't do that, I've never done that."
Jon: "Roll 212!"
*Video of guest doing "that"*
