The questions were written in advance by the producers.
Certain kinds of questions such as name, age, occupation, and income cannot be asked. The bachelorette would make her choice based solely on the answers to her questions.
The same question could be asked to multiple bachelors.
ABC dropped the show on July 6, 1973, but it resurfaced in several syndicated versions (1973–1974 as The New Dating Game, 1978–1980, 1986–19–1999; repeats of the last version appeared in the 1999–2000 season.) For years it would almost always be aired in tandem with another Barris production, The Newlywed Game, which premiered on ABC the following year.
Typically, a bachelorette would question three bachelors, who were hidden from her view; at the end of the questioning period, she would choose one to go out with on a date paid for by the show.
This is an episode of a silly 1960s game show where female contestants try to find the man of their dreams by asking three men a series of questions.
Mindless fluff, but at least it is better than "Blind Date".
