Hi Jay, Well.. if you have a bunch of ZClasses with the same behavior, say they can all do the cha-cha, you could just give them a property (canDoTheChaCha) and check for that. Then they don't need to subclass from anything in particular, so long as they conform to any cha-cha like behavior expectations. ;-) -steve
