Whose Line Is It Anyway? Australia

The show where everything's made up and the points don't matter. Not a talk show, not a sitcom, not a game show, Whose Line Is It Anyway? is a completely unique concept to network television. Four talented actors perform completely unrehearsed skits and games in front of a studio audience. Host Drew Carey sets the scene, with contributions from the audience, but the actors rely completely on their quick wit and improvisational skills. It's genuinely improvised, so anything can happen - and often does.

Comedian Aisha Tyler hosts this improv comedy show where the actors on the show - Wayne Brady, Colin Mochrie, Ryan Stiles along with a special guest each episode -must put their comedic skills to the test through a series of spontaneous improv games, prompted only by random ideas supplied by the studio audience.

David Letterman uses mature humor to appeal to his audience in this weeknight series, which gets its music from a house band led by Paul Shaffer.

This partially unscripted comedy brings viewers into the squad car as incompetent officers swing into action, answering 911 calls about everything from speeding violations and prostitution to staking out a drug den. Within each episode, viewers catch a "fly on the wall" glimpse of the cops' often politically incorrect opinions, ranging from their personal feelings to professional critiques of their colleagues.

Based on Scott Aukerman’s popular podcast of the same name, COMEDY BANG! BANG! cleverly riffs on the well-known format of the late night talk show, infusing celebrity appearances and comedy sketches with a tinge of the surreal. In each episode, Aukerman engages his guests with unfiltered and improvisational lines of questioning, punctuated by banter and beats provided by bandleader, one-man musical mastermind Reggie Watts, to reinvent the traditional celebrity interview. Packed with character cameos, filmic shorts, sketches and games set amongst an off-beat world, COMEDY BANG! BANG! delivers thirty minutes of absurd laugh-loaded fun featuring some of the biggest names in comedy.
