I Dan Harmon's Harmontown podcast, he and a few guests talk for an hour or so in front of a live audience and then finish the show by playing Dungeons and Dragons.
Episode 92 was recorded not long after the news came out that Ice-T had unwittingly agreed to narrate a Dungeons and Dragons audiobook. Coincidentally, the Harmontown group's usual dungeonmaster was out. So when it came time to play Dungeons and Dragons, they had an Ice-T impersonator DM in character as Ice-T.
