The Emmy-winning Comeback Kid himself comes back yet again with a blunt, brilliantly quotable stand-up special. "Baby J" takes the form of a wide-ranging conversation between John Mulaney, a kid in the balcony named Henry, and the rest of the sold-out crowd at Boston"s Symphony Hall. And now, you! John dominates the chat, of course - and while his cautionary tales are a bit too convulsive to be functionally preventative, you probably aren"t here to be cautioned. So have at it!
