    Code (csharp):
    1. Transform[] childs = gameObject.GetComponentsInChildren<Transform>();
    2. GameObject randomObject = childs[Random.Range(0,childs.Length)];

    I'm not sure just posting the complete solution to a trivial problem is the right approach, that's why I didn't.

    Yeah, here you go:
    Code (csharp):
    1. Transform[] childs = (Transform[]) gameObject.GetComponentsInChildren<Transform>();
    2. GameObject randomObject = (GameObject) ((Transform)childs[Random.Range(0,childs.Length)]).gameObject;
