This week on Here's The Thing, Alec talks with late-night legend David Letterman. Letterman describes his early years on TV, his decision to try radio and his eventual journey to LA where he found himself on "The Tonight Show" after just three years working in comedy clubs.

This week Alec talks with playwright Jon Robin Baitz, whose Broadway play, Other Desert Cities, is up for a Tony later this month. Baitz talks about the origin of the new play, his short-lived adventures writing for television in Hollywood, and the relief of coming back to the American theater.
