You can create overloaded methods:

void Foo(A a) 
{ 
    a.Hop(); 
}

void Foo(B b) 
{ 
    b.Skip(); 
}

void Foo(object o) 
{ 
    throw new ArgumentException("Unexpected type: " + o.GetType()); 
}

And cast the argument to dynamic type in order to bypass static type checking:

Foo((dynamic)something);
