Guest host Hope Davis presents three uncanny stories featuring children. In Simon Rich’s hilarious “The Baby,” a novelist faces competition from his unborn son. Jason Mantzoukas is the reader. A children’s game takes a strange turn in Fiona McFarlane’s “Buttony,” read by Jin Ha. And Etgar Keret offers up an unusual mother-son story—and lots of calories–in “Crumb Cake,” performed by Andy Richter.
