Celebrity sightings thus far in Manhattan: David Byrne today in the Builder's Association office where I'm workshopping the show Super Vision and Amy Poehler (pictured), Horatio Sanz and Seth Meyers in ASSSSCAT 3000 at the Upright Citizen's Brigade Theater, doing improv much funnier than most of their skits on SNL. And Chengwin. Oh, yes, Chengwin. How to describe the magic of Chengwin? Well...let's see...picture hundreds of people running through the streets of Soho waving pom-poms, cheering a half-chicken, half-penguin in his battle against his half-chicken, half-skunk nemesis Chunk. Aaah, Manhattan.
