A young, attractive woman decides to hang one of her favorite pictures on her wall and asks her father what she needs to do.
He says to hammer a nail with a large head on it into the wall where she wants her picture to be located.
After searching endlessly for a "nail with a large head on it" she gives up and goes out to buy one.
When she reaches the store she sees an old dirty looking man with his eyes popped out of his head once she enters the store. Not knowing her way around a hardware store she is forced to ask him for help.
"Do you have a nail with a large head on it?"
He answers, "I have something with a large head that would be happy to nail you."
