Jon Stewart plans to return to stand up comedy in a special for HBO. It will be the former ?Daily Show? host?s first such special in over 20 years. The news was announced Wednesday at the TCA summer press tour. Stewart?s last stand up special, ? Jon Stewart: Unleavened,? aired on HBO in 1996. He is under a four-year production deal with HBO, which he signed in 2015. Stewart initially planned to produce a short-form digital animation project for the network, but those plans were scrapped in May.
