Prankery Most of us at least once in my childhood were joking on the phone, playing their friends or strangers by typing their numbers at random. Today, telephone joke became fashionable name - the prank, which translates to English as a practical joke, prank. The emergence of prank is directly related to the introduction of telephone communication in our daily lives. Before the invention of automatic stations, operators manually connected the subscriber line. And, here in one of these companies, which would distract from the monotony of work, operators began to make fun of subscribers, connecting them with the wrong numbers, they are requesting, or were answered by another person. Of course, it soon was discovered by management, and pranksters were fired. Later, in the 80 years there were Fricker, who loved to make fun of subscribers randomly dialed. But it was, as a rule, without a break, on an amateur level. Speaking of records, why the current record their phone prank joke on tape? It's simple. Now the World Wide Web allows you to express yourself in any forms. As they say, "Who's that much." On the web, there are special bazaars prank sites where archives of records lined with the victims. And some DJs to create remixes, use insert "phone works." Victims of phone pranksters usually are people who are emotionally unbalanced, without a sense of humor and high self-esteem. This manifests itself in violent reaction to provocation caller when the victim ceases to control myself and soon goes to talk to a hysterical abuse and threats. Such subscribers - a godsend for the prank, after all hate it and eats it all, he carefully recorded and posted on the Internet on all the fun. Not uncommon for victims of prank are law enforcement officers, pensioners, politicians. Especially popular among the prank are pop stars of show business - Boris Moiseev, Philip Kirkorov, Dima Bilan, Ksenia Sobchak.
