Two farmers from a small town outside of Little Rock, 
Arkansas were walking home together after each purchased a 
pig. One said to the other

-"How are we going to tell them apart?" The other answered,
-" We'll cut the left ear off of yours."

After a while the pigs got in a fight and after 
they had both bitten off each other's ears. 

-"Now what are we going to do?" one asked to the other.
-"We'll cut the tail off of mine."

A little while later the pigs got in another fight and at the
end of it they both were missing their tails. 

-"What will we do now?" one asked again. After giving it some 
thought one said

-"We'll cut the leg off of yours."
-"That is not humane!" the other cried. 

So after some more thought he said

-"Well, lets just call the white one yours and the black one mine."
