Bob was cruising in his Porsche on a country road, just south of
Murfreesboro, TN.  It was a beautiful day, the temperature about 75
degrees, and there was a light breeze.

His attention was drawn to the rearview mirror by some movement, and
looking intently, he noticed what looked like some animal rapidly
approaching.  He was driving about 50 miles per hour, but the white
creature appeared to be getting closer and closer.  He continued to
check the mirror, and finally realized that what he was seeing was a
chicken.

The chicken continued to gain, and eventually pulled alongside the
Porsche.  Looking closely, he noticed that the chicken had three legs.
The chicken cruised alongside him for a while; Bob pressed the
accelerator pedal, and sped up to about 65 mph.  The chicken stayed
right beside him for a while, occasionally turning and looking in the
Porsche's side window, then gradually passed him and sped away.

Bob pulled in behind the chicken, but the chicken continued to pull
away.  Suddenly, the chicken turned onto a tree-covered gravel lane.
Bob followed the chicken down the lane for about a mile, and, all of a
sudden, the lane opened into a meadow, and there were what appeared to
be hundreds of chickens running around, all with three legs.  He noticed
a farmhouse adjacent to the meadow.  The farmhouse had a big front
porch, and a man wearing bib overalls was sitting on the porch in a
rocking chair.

He stopped the car, walked up to the old man on the porch, and said
hello.

The old man said, "Hi, can I help you?", as he chewed on a straw. 

Bob explained that he had been out for a drive, and that he had been
passed by the chicken.  He said, "I don’t mean to bother you, but that
chicken piqued my curiosity, and I just had to find out more about it.
Now, I see, there’s a bunch of them!"

The old man chuckled and said, "Yes, sonny, these chickens pique a lot
of folks' curiosity.  You see, I worked for years as a researcher at the
genetics lab at Vanderbilt University.  I have three boys, and my wife
makes a mean fried chicken.  However, all three of the boys would want a
drumstick, whenever she fixed fried chicken.  One thing lead to another,
and I decided to try my hand at growing three-legged chickens, so each
of the boys could get a leg."

Bob said, "That’s pretty remarkable.  How do they taste?"

The old man said with a smile, "I don't know.  We’ve never been able to
catch one."
