Drew Carey hosts the hilarious "Whose Line is it Anyway" (adapted from a British show of the same name). In this show, four actor/comedians (usually Colin Mochrie, Wayne Brady, Ryan Stiles, and a "wildcard") act out improvisational comedy skits.
These skits are hilarious! My wife and I will sometimes be in tears laughing at these incredibly skilled actors who can do amazing improvisational comedy. They also have a great rapport with each other, which is probably the key to the show.
That being said, the first season doesn't quite live up to the later seasons. Some of the skits ("games") were a bit lame and not that funny - it's as if the writers were still searching for the best ideas for the show. And don't get excited about the "Uncensored" label, because little if anything in this season was actually censored, so you won't see anything that you haven't already seen.
Still, it's a side-splittingly funny show with a fabulous cast and should be must-buy for anyone.
