Dave Attell is the perfect host for Comedy Central's Comedy Underground. Presenting the uncensored, no-holds-barred comedy showcase was a natural fit for Attell, who is never one to hold back on vulgarity in his routines. Now he's taking his filthy mouth on the road and bringing the belly laughs on tour!

Also known as Erlich Bachman in HBO sitcom Silicon Valley and Wade Wilson's wise-cracking friend in Deadpool, Miller is an accomplished comedian and actor. Known for his deadpan zingers and semi-stoner persona, he's not afraid of controversy (that Uber ride, and the gig in Puerto Rica), often stirring the pot with absurdist observational standup act for over 10 years. In addition, he has also lent his raspy voice to animated hits How To Train Your Dragon 1 and 2 and Big Hero 6.

Is there no end to this man's talents? Popularly known as the "Roastmaster General", this insult comic is well-known for his regular appearances on Comedy Central's Roasts and has also appeared in various film, television, and cartoon projects, as well as directing documentaries and authoring books.
