This is hilarious. I hadn't heard of it before.
Mortified stars everyday adults reading aloud their most embarrassingly real teenage diary entries, poems, letters, lyrics and locker notes...in front of total strangers.
Not the same, but not totally unrelated is The Moth, a great storytelling series in NYC. I was privileged to curate an evening in June 2001. Titled In the Dark, Filmmakers Illuminate, it featured Peter Hedges, Bingham Ray, Caroline Kaplan, Darnell Martin, and Pamela Yates.
There's nothing like a good story well told.
