Using "Tag" to disable Rigidbody Constraints

I cant figure this out for the life of me. How do I correctly reference all the tagged objects and remove the reigidbody constraints from them?

	//Cause the menu to FALL to the Ground
	GameObject.FindGameObjectsWithTag ("MainMenu");
	rigidbody.constraints = RigidbodyConstraints.None;


You have to store the reference that FindGameObjectsWithTag returns, then loop through them and do your thing.

GameObject[] gos = GameObject.FindGameObjectsWithTag ("MainMenu");
foreach (GameObject go in gos)
    go.rigidbody.constraints = RigidbodyConstraints.None;
