Two brothers, Bill and Morty, loved to sail. Every weekend, they would go for a few hours on the lake. Known the world over, they taught people together many times.

One day, Bill was required to sail across the lake without Mort in order to pick up a student for a day of sailing. However, Bill was unable to make the crossing. When they finally located Bill and the sail boat, they found him tangled in the riggings.

On closer examination, they found that Bill is not the rigger Mort is.
