YOU SO SMART?

Mensa is an organization whose members have an IQ of 140 or higher and a few years ago, they held a convention in San Francisco, where several members lunched at a local cafe.

While dining, they discovered that their saltshaker contained pepper and their peppershaker was full of salt. Clearly this was a job for Mensa! How could they swap the contents of the bottles using only the implements at hand without making a mess?

The group debated, formulated theories, and finally came up with a brilliant solution involving a napkin, a straw, and an empty saucer. Then, they called the waitress over to dazzle her with their inventiveness.

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

"Oh," the waitress interrupted. "Sorry about that." She unscrewed the caps of both bottles and switched them.
