This is happening, and it will be something to see/hear:

Fran Lebowitz: Public Speaking, A Conversation with Dan Savage and the Audience will be at Benaroya Hall’s Mark Taper Auditorium on March 2, 2012 at 8:00pm and plans to unite these two dynamic, sardonic social commentators on stage have been in the works for months. Together, they have agreed to have a little chat and take questions from the audience.
