Ludwig

Ludwig Wittgenstein asked this peasant woman, "What is your name?"
She replied, "Tamara."
He asked, "Why can't you tell me today?"
She replied, "Because I don't have the name Today."
He said, "You must have the name today."
"I told you, Tamara."
"Well tomorrow will be today tomorrow."
"No it won't," she said, "it will still be Tamara."
"Then I will never know your name," said Wittgenstein.
She said, "You're stupid, you are."
So Wittgenstein decided to become a school teacher.
