Obvious relationship
Science has a language of its own which sometimes puzzles laymen. The word "obvious" is a case in point.

A professor of physics, deriving some profound point of theory for the class, scribbled an equation on the board and said, "From this, it is obvious that we can proceed to write the following relationship, " and he scribbled a second and equally long equation on the board.

Then he paused. He stared hard at the two equations and said, "Wait a minute, I may be wrong, "

He sat down and began to write at his desk furiously, crossing out and rewriting for five minutes while the class sat in absolute silence waiting for the verdict.

Finally, the professor rose with an air of satisfaction and said, "Yes, I was right in the first place. It *IS* obvious that the second equation follows from the first."

just the way one silly thought followed into ur mind after the first

arrant nonsense i dint even understand the basis of the damn joke

this is tutology
