Thank you! Excelent code!
But I discovered that if you attach the Shake() method to a object, in my proyect to a GUI Button, if you click too much, the object changes it's original position, so I put a bool isShaking for controlling when it's shaking or not, and maybe if someone needs it, here is the code! :

using UnityEngine;
using System.Collections;

public class ObjectShake : MonoBehaviour
{
    private Vector3 originPosition;
    private Quaternion originRotation;
    public float shake_decay = 0.003f;
    public float shake_intensity = .2f;
    public bool isShaking = false;

    private float temp_shake_intensity = 0;

    void Update()
    {
        if (temp_shake_intensity > 0 && isShaking == true)
        {
            transform.position = originPosition + Random.insideUnitSphere * temp_shake_intensity;
            transform.rotation = new Quaternion(
                originRotation.x + Random.Range(-temp_shake_intensity, temp_shake_intensity) * .2f,
                originRotation.y + Random.Range(-temp_shake_intensity, temp_shake_intensity) * .2f,
                originRotation.z + Random.Range(-temp_shake_intensity, temp_shake_intensity) * .2f,
                originRotation.w + Random.Range(-temp_shake_intensity, temp_shake_intensity) * .2f);
            temp_shake_intensity -= shake_decay;
        }
        else
        {
            isShaking = false;
        }
    }

    public void Shake()
    {
        if (!isShaking)
        {
            isShaking = true;
            originPosition = transform.position;
            originRotation = transform.rotation;
            temp_shake_intensity = shake_intensity;
        }
    }
}

Thanks a lots for this code. Nice Bro!

thanks much - worked perfectly!
