It was really, really, hysterically funny making a hoax call from Australia at about 05.30 London UK time, to an unsuspecting member of nursing staff at the hospital treating the Duchess of Cambridge for acute sickness in the early stage of her pregnancy. It was too damn easy because the person taking the call would not have had sufficient aural expertise to assess a poor impersonation of the Queen or Prince Charles, and, yes, the impersonation was bad to the ears of any native UK English speaker, which, the nurse was not. Bear in mind, we, the public, probably heard the recording improved for clarity of broadcasting.
The next day, the same two, really, hilariously, funny media presenters, gloated over their success, oh, and how easy it all had been. By the way, you idiotic selfish, inane, individuals, actions have consequences. The poor unsuspecting innocent nurse, (a mother of two children) who took the call, has now killed herself.
