Some years ago, there was an Engineering Convention in San Francisco .  This was only for people who had an IQ of 140 or higher.

        Several of the members went out for lunch at a local cafe. When they sat down, one of them discovered that their salt shaker contained pepper and their pepper shaker was full of salt.

        How could they swap the contents of the two bottles without spilling any, and using only the implements at hand?
        Clearly this was a job for engineering minds.

        The group debated the problem and presented ideas and finally, came up with a brilliant solution involving a napkin, 2 spoons, a straw, and an empty saucer. They called the waitress over to dazzle her with their solution.


        "Ma'am," they said, "we couldn't help but notice that the pepper shaker contains salt and the salt shaker contains pepper."

        But before they could finish, the waitress interrupted them. "Oh, sorry about that." She leaned over the table, unscrewed the caps of both bottles, and switched them.
        There was dead silence at the table.
        This reminds me of our government.
