Jon Stewart announced that Amy Schumer, Denis Leary and Louis C.K. will be his final guests on "The Daily Show."Stewart made the announcement on Thursday night's episode of the Comedy Central show."Remember, next week is our last week," Stewart said at the end of the episode. "I can't wait to show my appreciation at all the support and enthusiasm that you guys have given this show all these years, so thank you all so much. Next week, tune in, it's going to be a ball."Stewart announced in February that he would be departing "The Daily Show" after 17 years as host. He will be replaced by comedian Trevor Noah, who recently spoke about the pressure he feels in taking over the institution."The biggest pressure for me is living up to the expectations that Jon has of me," Noah said. "Jon believes in me ... There's an immense pressure for me personally to live up to that legacy to keep that flagship going. It don't think of it (as being) about me. It's about the show first."Among the Stewart fans most devastated by his sign-off is President Obama, who visited "The Daily Show" for the last time earlier this month and threatened to use his presidential pull to keep Stewart from leaving."I'm going to issue an executive order," Obama said. "Jon Stewart cannot leave the show. It's being challenged in courts."Stewart's final episode of "The Daily Show" will air August 6 on Comedy Central.
