Whose Line Is It Anyway, where the games are made up and the points don’t matter. This show is all improvisation, and the actors and guest stars come up with situations and ideas off of the top of their heads. The show was originally aired in the UK, but grew popular with America and made its own. Whose Line was cancelled for a few years, but has made a huge comeback. It stars Wayne Brady, Ryan Stiles, Colin Mochrie, and is hosted by the lovely Aisha Tyler (instead of former host Drew Carrey). It airs Tuesdays at 7pm on the CW Network.
