In our younger days, there were jokes about Sir Isaac Newton.
Later, there were jokes about Albert Einstein.
It is possible that someone made or modified a joke about an absent minded professor and then attributed to a famous person.
It was raining.
Einstein took off his hat and hid it in his coat.
A student asked “Why?”
Einstein’s reply : “My hat is new and can be damaged. But my head cannot be damaged by the rain.”
A ticket inspector boarded a train.
Einstein searched for his pockets.
The inspector said, “You need not show me the ticket. You are Einstein.”
Einstein’s reply : “I do not know which stop I should get down.”
Einstein was carrying a stack of books.
He collided with a beautiful student.
The books fell down.
The student collected the books and returned them to Einstein.
Einstein asked, “Which way was I going?”
The student replied, “You were going towards the school.”
Einstein felt relieved. “Then, I must had my lunch at home.”
