Un, dos, tres... responda otra vez (1972)

This was a three-part contest. In the first part, three male/female couples had to give the most correct answers to the questions they were given. The more answers they gave in 45 seconds, the most money they earned. Each couple was given three questions. When they gave a wrong answer or repeated any of the previously-given ones, the miserlies, who hated to see the contestants win money, rang a bell and made them stop answering. The couple with the most money returned the next week, and other two went on to the next contest, which was a test. The winning couple went on to the best part of the program: a show of music, humor, and surprises. When each performance was finished, an object related to it was taken to a table. Each object had a card with a prize. The host read a part of the card and the couple had to figure out the rest. When there were three objects on the table, they had to leave one in order to bring more. The host read the rest of the cards and the prize was revealed. In the end, they had to choose one of the three last objects to keep it, usually big prizes like cars and trips.
