Shows like "An Inconvenient Talk Show" are the black sheep of the New York comedy scene, which is known for its unapologetic and groundbreaking stand-up, topical sketches, and its weird but enduring love affair with improv. Having seen nothing like this before, I had my reservations. Initially, the seriousness of the subject matter worried me; would it give the audience a good laugh, or leave us under a dark cloud of despair? However, when I plopped myself at a table close to the Caveat stage and saw it set with a simple desk, a modest stack of Al Gore books, a globe, and - best of all - an inflatable dolphin suspended from the ceiling, I knew we were in for a treat.
