Josh was the male star of the show TGS before Tracy was hired. Liz found him while he was opening for a puppet. He, Tracy and Jenna Maroney are the three main actors on the show. It has also been said that his character is based on SNL alumnus Jimmy Fallon. Apparently, Josh also acts as a writer as well as star of the show, as he is frequently seen in the writers room brainstorming, whereas Jenna is not. Most of Josh's work on the show seems to be as an impressionist; he has performed impressions of Ray Romano, Michael Jackson, Stone Phillips, and Jay Leno.
