Java: How to call super().super() in overridden method (grandparent method)

Possible Duplicate:
Why is super.super.method(); not allowed in Java?

I have 3 classes they inherit from each other as follows:

A
 ↳
   B
    ↳
     C

Inside each class I have the following method:

protected void foo() {
    ...
}

Inside class C I want to call foo from class A without calling foo in B:

protected void foo() {
    // This doesn't work, I get the following compile time error:
    // Constructor call must be the first statement in a constructor
    super().super().foo(); 
}

EDIT
Some Context Info:
Class B is an actual class we use. Class C is a unit test class, it has some modifications. foo method inside B does some things we don't want so we override it inside C. However foo in class A is useful and needs to be called.
