One day little Johnny runs into the corner store and asks for some dog food.

The clerk decides to have a little fun at Johnny's expense and says, "Ok Johnny, first show me a dog, then I'll sell you some dog food."

Little Johnny runs home, gets the dog and takes it back to the store and the clerk sells him the dog food.

The next day little Johnny comes in and asks for some cat food. The clerk says, "first show me a cat." Little Johnny walks home, brings the cat, gets the cat food and leaves.

The next day little Johnny comes in and asks for some bird seed. The clerk says, "You know the drill...show me a bird first."

Little Johnny looks at the clerk for a full minute, but he goes and gets the bird, gets his bird seed and goes home.

The next day, little Johnny comes in with a bag and tells the clerk, "Quick, stick your hand in here!"

The clerk puts his hand in the bag, pulls it out and asks, "What is this, sh-t?"

Little Johnny says, "Yes...I need some toilet paper."

I love little Johnny
