Every morning when they come to work they lock the door of the office and, armed with binoculars and great interest, they begin watching the aerobics exercises of a young girl in the nearby building. Suddenly, their tranquil daily round is disturbed - a new director takes over the Institute and decides to develop close scientific partnerships with similar institutes in Japan. A rumor has it that one of our three friends will go on a business trip there. But who? The three friends are now rivals. "Homo homini lupus est"! All the three undertake sophisticated underground maneuvers in order to get the prize. Everything is at stake! There is only one rule and it is there are NO rules! At the end, of course, it turns out everything has been in vain. The one to go to Japan is the director.<br>Numerous situations filled with humor follow and, at the very end, after the grotesque outcome, we can see the three friends together again. But this time, much wiser… perhaps.

Document 10: Blue Peter pets: The Blue Peter pets are animals that regularly appear on the long-running BBC children's television series "Blue Peter". For 27 years, when not on TV, these pets were often looked after by "Blue Peter"'s long-standing pet keeper Edith Menezes, who died in 1994. The first pet was a dog named Petra in 1962, and since then there have been several dogs, cats, tortoises, and parrots, and horses Joe And Simon. The current animals on the show are Shelley the tortoise and Iggy the trainee guide dog puppy. Rags, a pony, named by viewers, was purchased with the proceeds of a Christmas appeal in the late 1970s as a Riding for the Disabled horse. The Blue Peter parrot—Joey, and one successor, Barney—featured in the 1960s, but when Barney, a blue-fronted amazon, died, he was not replaced. In a 1986 documentary shown on BBC2 as part of the Did You See...? series, former presenter Peter Purves recalled that Biddy Baxter, the show's editor, had called him in floods of tears the day the first parrot Joey died. He went on to muse in the same interview that had he himself died, Baxter would have been far less upset. The original ideas behind featuring the programme's pets were to teach viewers who had animals of their own how to look after them, and for the creatures to act as surrogate pets for those that did not own any. For example, dog training items, tortoise hibernation, and cat care are often featured on the programme; however, the keeping of rabbits and mice was deemed not suitable as they do not live long. In addition, dogs that lived with the presenters often accompanied them on filming assignments.
