One day in the park ...

A pretty young girl is walking her doggy. 

A woman sitting on a park bench is so charmed by the sight, she exclaims, "Little girl, you look so pretty!"

The girl says, "Thank you ma'am. My Mommy did my hair extra special today."

The women: "And, that's such a cute dress!"

"Yes", says the girl. "My sweet Aunty sewed it especially for me!" 

"And, what a nice little doggy!" 

"Yes", the girl adds, "he's my best friend in the whole wide world!"

"What is your puppy's name?"

"His name is 'Porky'."

The woman remarks, "That's a interesting name for a dog. How come you call him 'Porky'?"

The most darling, pretty little girl responds, "We call him 'Porky' because he likes to fuck pigs!"
