- Joey leaves the contents of his bank account "to my employees." If Joey then fires some of the old employees and hires new ones, the new employees will inherit the contents of the bank account under this provision.

- Joey writes in his will, "I leave my car to Rachel". Joey drives an old car at the time of the testamentary instrument, but later sells the Gremlin and purchases a new car. Because Joey bought a new car to get a more comfortable ride, rather than to change a will without going through the testamentary formalities, the gift to Rachel remains enforceable.
