A traveling salesman is driving down a deserted country road when he has a blowout.
Not having a spare he finally finds a house and asks the lady if he can use her phone to call for a tow-truck.
As she opens the door for him to come in, a Three Legged Pig runs out.
He asks "why does that Pig only have three legs?"
She says that they had a fire and the pig woke everybody up and then went back and brought the dog out.
He said "but why does the Pig only have three legs?"
She said well another time my son was playing on the ice and it broke and he fell in and the Pig ran to the barn and got a rope and saved him.
Again he asked "why does the Pig only have three legs?"
After all the Pig did for us, it didn't seem right to eat him all at once.
