Q: Person1: Good morning golf aficionados ! My name is Rick Fields , and you guessed it , I am here with my main man , Bob Copeland .
Person2:Thank you , Rick ! As you can see , ladies and gentleman , we are here in beautiful Pebble Beach where the top golfers in the world are trying to win the grand prize of one million dollars !
Person1: Whoa , that ' s a lot of cash ! Let ' s go to the course and see how Tiger Woods is doing .
Person2:All right , we are here at the eighth hole . It ' s a par four , and has some very difficult hazards which many golfers find difficult to avoid . Although , I did see Jack Nicklaus hit a hole in one on this very same hole !
Person1: Tiger Woods is about to tee off , and let ' s see if he has the same luck as Jack . Tiger is asking his caddie for his driver and , he seems to be very nervous .
Person2:Oh no ! Not a good swing at all ! It ' s definitely not his day today . On the seventh hole he got a bogey and before that he barely made par . He will definitely not get a birdie on this shot .
Person1: It seems that his ball has flown somewhere deep in the trees . He is having a hard time finding it and even his caddie has climbed a tree to try and spot it .
Person2:Oh no ! A bear ! Run , Tiger , run ! Somebody call animal control !

A: informal
