Welcome to the official 'Whose Line Is It Anyway?' YouTube channel, where you can find all of the best bits from the latest version of the show, hosted by Aisha Tyler, with returning veterans Ryan Stiles, Wayne Brady and Colin Mochrie. If you're in the UK head to Comedy Central to watch full episodes of the show - link below! Each episode, a special guest star joins the comics as they tackle a series of spontaneous improvised sketches, with only a few random ideas from the studio audience and their host. With little information and a lot of imagination, the comics depict a variety of characters and scenes, and even perform songs. At the end of each round, Aisha awards points to each of the four performers and announces a winner at the end of every episode.
