I'm envisioning a nice little skit that a Don Box or someone like that could pull off on stage. Don't worry there are no bath-tubs or naked presenters involved. It is along the lines of the typical malevolent computer/robot on StarTrek that is defeated by a paradoxical question. In this case, it is to explain the rules of GetHashCode() i.e.:
Kirk: "Com .. puter ... what ... are the rules ... of GetHashCode()?" Computer: "GetHashCode() must always return the same value. GetHashCode() must return the same value for objects that are equal." Kirk: "But ... com .. puter, how can GetHashCode() ... always return ... the same value if I ... change ... the value of the object .. thereby guaranteeing it is no longer equal to ... its ... original value?" Computer: "GetHashCode() must always return the same value. GetHashCode() must return the same value for objects that are equal. If the second object's equivalence with the first object changes then the objects are no longer equal and the second object should return a different hashcode to get the best hash lookup performance. But GetHashCode() *must* always return the same value... This is not logical! Error! Error!
