"Prank calls are the new lowest form of wit." John Lloyd, comedy impresario, in today's 'i' (silly name).
If they can be be styled 'wit'. To me they are a form of bullying. They are the instrument of the irresponsible used in the main against people who have no defence mechanism and no means of redress. Only a sadist would regard such invasions as a form of entertainment.
