At the conclusion of each episode, a winner or several winners were chosen arbitrarily by Carey.
The "prize" was either to play a game with the host, or to sit out while the other performers did so.
The original host Drew Carey awarded arbitrary point values after each game, often citing a humorous reason for his decision.
The points were purely decorative and served no practical purpose.
The show turned into an inexpensive hit (though less so than the British version), and ABC kept Carey on as host.
Some featured all four performers, while others featured fewer.
Between games, the performers sat in four chairs facing the audience.
This approach to reading credits was pioneered by the earlier BBC radio show I'm Sorry, I'll Read That Again.
Indeed, the title of the show itself is a comedic riposte to another radio show, What's My Line, merged with the title of a 1972 teleplay (and eventual theatrical play) Whose Life Is It Anyway? The radio series lasted for six episodes, after which Channel 4 developed the franchise for television.
