Did you read about the 6 foot 10 inch tall tennis player?
gpt
No I didn't.  Where's he from?
human
He is American.  He played the longest duration match at Wimbledon in history of 11 hours 5 minutes
gpt
Wow!  I wonder if he won.
human
*relaxed posture* No. Even though he has a booming serve, he lost.
gpt
*lips slightly parted* Too bad.  I don't know much about tennis but i have heard of Wimbledon.  Was that where the match was?
human
I was mistaken, He won that one.  It is in England.  The Queen sometimes attends and other royals do also.
gpt
That's pretty cool.  I've heard of Serena Williams playing there.
human
In 1998, she and her sister claimed they could beat any man ranked 200 or worse.  A guy who was ranked 203 beat them badly.
gpt
*relaxed posture* That's good to know.  I think she is ranked behind Stefi Graf and Martina navratilova.
human
*hands at sides* She has had some trouble coming back after delivering her child.  
gpt
I don't like the yelling she does when she hits the ball.  Some people consider that cheating.
human
It certainly is distracting.  Others have imitated it also.  Even kids imitate their heroes.
gpt
Yes they do.  Did you know that up until 1978 a player could use anything as racket?
human
No.  That is radical.  I wonder if any peculiar things were used?
gpt
*eyes brighten* I would like to see a Wimbledon match from before 1978 to see if anything odd was used!
human
*calm eyes* I can't think of anything that would be better.  Perhaps a baseball bat for serving.
gpt
Maybe a light frying pan?
human
Good thought.  There must be something that would produce more speed and still be accurate.  I would rather be hit with a tennis racket than a frying pan
gpt
Me too!  Speaking of being hit, did you know that the NFL is not a sport but an entertainment industry?
