premise: "Cake Train" is the first episode of the second season of the American sketch comedy series "Kroll Show". The episode was written by series creator Nick Kroll, along with Jon Daly, Ron Funches, Carol Kolb, Jonathan Krisel, John Levenstein, Gabe Liedman, Joe Mande, Christine Nangle and Joe Wengert. In the United States, the episode originally aired on Comedy Central on January 14, 2014.
hypothesis: Nick Kroll wrote for the first season of Kroll Show
reason: While it is easy to assume that Nick Kroll wrote for the first season of his own show, the context doesn't specify that-- he may well have been the star of the show originally, and joined the writers in the second season.
