play an audio clip from a GUI button

Hello I am trying to play an audio clip from a GUI button. The button already plays an animation when pressed. How do I script it to also play the sound. This is the code for my GUI button. Thanks.

function OnGUI () {

if (GUI.Button (Rect (10,130,70,20), "BLUE")) {

animation.Play("car2");

    }

}

You will need to make a reference to the audioclip, and the object with the script on it will need to have an audiosource on it.

Then right below the line that says animation,play, I would put audio.playoneshot().
