Prove that the Chair Does not Exist

A philosophy professor walks in to give his class their final. Placing his chair on his desk the professor instructs the class, "Using every applicable thing you've learned in this course, prove to me that this chair DOES NOT EXIST."

So, pencils are writing and erasers are erasing, students are preparing to embark on novels proving that this chair doesn't exist, except for one student. He spends thirty seconds writing his answer, then turns his final in to the astonishment of his peers.

Time goes by, and the day comes when all the students get their final grades...and to the amazment of the class, the student who wrote for thirty seconds gets the highest grade in the class.

His answer to the question: "What chair?"

Perhaps Not a Bridge

A philosopher went into a closet for ten years to contemplate the question, What is life? When he came out, he went into the street and met an old colleague, who asked him where in heaven's name he had been all those years.

"In a closet," he repied. "I wanted to know what life really is."

"And have you found an answer?"

"Yes," he replied. "I think it can best be expressed by saying that life is like a bridge."

"That's all well and good," replied the colleage, "but can you be a little more explicit? Can you tell me how life is like a bridge?"

"Oh," replied the philosopher after some thought, "maybe you're right; perhaps life is not like a bridge."
