Virtual functions

What, pray tell, is the purpose of a virtual function? Also, why would you implement a "virtual" method? It just doesn't make sense.

It is named virtual because the faggots who came up with this shit wanted to come up with the vaugest keywords possible.

You faggots are too stupid to appreciate VB.Net. In VB.Net if an inherited class must override a given method, the method is declared as MustOverride in the base class. You know, because you don't have to virtual the method, you have to override it.
