"Mortified" is a stage show and a TV show on the Sundance Channel which encourages people to share their most embarrassing poems, stories, songs, tapes and more with an audience. Creator Dave Nadelberg says he's especially interested in people demeaning themselves to give the audience both pleasure and pause.  For Mortified, almost nothing is off limits. Don Merrill talked with Dave Nadelberg about the surface laughs and the deep questions around Mortified.
