Inadequate. Within three months of its release, Norton was touring with a new hour of material. In the following year, Norton described his career as "stagnant... there's nothing happening". In 2017, Norton's special A Mouthful of Shame debuted on Netflix. He promoted it with the 31-date Mouthful of Shame Tour, his first nationwide theatre tour as headliner, throughout 2016. The special includes an opening with Robert De Niro spanking Norton's bare bottom. Later in 2017, Norton embarked on his first stand-up tour of Europe. He signed with WME to pitch ideas for his own series on Netflix. He appeared in Season 2, Episode 1 of the Netflix standup comedy series "The Degenerates", released on 31 December 2019. Radio and podcasts In early 2001, Norton was hired as the third mic on the Opie and Anthony radio show on WNEW in New York City, with hosts Gregg "Opie" Hughes and Anthony Cumia. He resisted calling himself a "host" of the show as he believes his strongest performances were when he was "an outsider looking in". He first appeared on the show in 2000 with Clay during his time opening for him on tour and became a regular guest and sat in on some shows. In November 2000, Norton was arrested with comedian Lewis Black and show producer Rick Del Gado during their live reports on board the Teen Voyeur Bus, a transparent bus of topless women driving around the city. It so happened that the bus' route was also the route that President Bill Clinton was taking that day, but the show was not informed of the news. Norton spent the night in jail. In August 2002, the show was cancelled following the controversial Sex for Sam 3 segment and remained off the air for two years. Norton returned to the radio with Hughes and Cumia on XM Satellite Radio, an uncensored satellite radio service, in October 2004. Cumia said Norton contributed a "dark and perverse" side to the show. In October 2008, Norton was sued by New York City attorney Roy Den Hollander over his treatment during a phone interview on Opie and Anthony. In August 2009, The New York Post reported that Hollander was willing to drop his suit if Norton would also drop his motion to have Hollander sanctioned for filing a baseless claim, as well as being forced to pay Norton's legal fees.
