To tell the truth

Plot: The program exists since 1963, in which four well-known panel members participated. In this season as well, celebrities have to ask smart questions to the people in front of them, so that they can guess what profession that person has. Each panel member has only one minute to ask all their questions, which is not always easy. The celebrities cannot prepare for the quiz, but they are so curious that they learn a lot about the candidates. If a celebrity knows an answer, he or she can show the sign with the number of a participant, 1, 2 or 3. Then the real candidate must stand up, so that the panel of 'Who of the Three' knows if they have picked the right candidate.
