This is chronicling the radio version of What's My Line?
In each What's My Line? game, a contestant would enter the stage and sign in his/her name, by virtue of the host saying, "Will you enter & sign in please?" After that, he/she sat down at a desk next to the host. The game would begin by having the home audience be shown what's his/her line, and the host afterwards told the panel a clue which is usually "deals in a service" or "self-employed", something like those. Now the panelists in turn asked yes-or-no questions to the contestant which would hopefully lead to the right line. Each time the panelist in control got a yes answer, his/her turn continued, but if at any time the panelist in control got a no answer, he/she loses his/her turn and control passed to the next panelist in line; the contestant will also receive $5. Upon a no answer, the host would say the famous catchphrase "# down, # to go" (Ex: 2 down, 8 to go). Sometimes a question would have the host make a brief explanation which can lead to either a yes or no answer. A panelist can be allowed to pass his/her turn without penalty; other times the panel can call a conference. If the panel can guess the right line, they won the game, but if they got ten no answers, the contestant stumped the panel and won the game and a maximum total of $50. Often, the host would throw the cards over (end the game) when time was running short or any other reason.
