A boy was walking down the street with his Dad and noticed a dog mounting another dog.
The boy asked his Dad, "Hey Dad, what are those two dogs doing?"
"Well son, the dog on top's front paws are sore, so the dog on the bottom is giving him a ride home."
The son thinks it over, and then comes to the conclusion,
"Geez Dad, isn't that just like the world today… you help someone out, and you end up getting fucked."
