Have you been mortified lately? David Nadelberg stumbled upon the sweet angst of public humiliation when he read an old love letter aloud to friends in his mid-twenties. He then made the (not quite so) obvious conclusion that others might be interested in doing the same sort of thing. In 2002, Nadelberg launched “Mortified,” the longest and largest running stage show of its kind. He’s recently published a companion anthology called “MORTIFIED: Real Words. Real People. Real Pathetic.” (Simon Spotlight Entertainment, 2006). David Nadelberg will join us this hour.
