Calling for backup A policeman patrolling Kings Cross spots a huge black guy dancing on the roof of a Ford Sierra. He gets on the radio and calls for backup. ""What's the situation?"" ""A big fat darkie is dancing on a car roof.""You can't say that over the radio!"" replies the operator, ""You have to use the correct terminology as they taught you on the radio course at the police academy"" ""OK"" he says, ""Kilo... Zulu.... Tango.... Sierra....""
