just seen something on the internet, on a site about Great White Sharks.  It's a bit rude about Aussies, I'm afraid.  Apparently Jacques Cousteau built this swimming machine, disguised as a great white shark, so it could mingle freely with the other great white sharks and gather information.  Mr C has this to say about the other sharks' apparent attitude towards his "shark" which was named Troy. 
Since Troy cannot respond in a sophisticated, sharklike manner, Cousteau decided that while the great whites do buy that he's a shark, they consider him more like a "retarded cousin from Australia."  
Not very nice, eh??
