There was a Mensa convention in SF. (Grandpa's joke)

>
> Some years ago, there was a Mensa convention in San Francisco. Mensa, as you know, is a national organization for people who have an IQ of 140 or
> higher.
> Several of the Mensa 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 Mensa minds.
>
> The group debated the problem and presented ideas and finally, came up with a brilliant solution involving a napkin, a straw, and an empty saucer. They
> called the waitress over, ready 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 "
>
> But before they could finish, the waitress interrupted. "Oh -- sorry about that." She leaned over the table, unscrewed the caps of both bottles and
> switched them. There was dead silence at the Mensa table.
> Reminds me of our government, solutions would be so simple, but the brilliant minds in Washington have to make the situation difficult.

My grandpa emailed me this joke, I copied it exactly as written.
