you can try this:

 var showMsg = false;
 var msgText:string = "";
 
 function OnGUI()
 {
      if(showMsg)
      {
           GUI.Label(Rect(100,100,200,100),msgText);
      }
 }
 
 function ShowMessage(msg:string,duration:float)
 {
      showMsg = true;
      msgText = msg;
      yield WaitForSeconds (duration);
      showMsg = false;
 }
 
 // you can call ShowMessage() from anywhere you want, I have called on Start()
 function Start()
 {
     ShowMessage("This is your message",2);
 }

That all makes sense thanks. One further silly question. Where do I put/attach this script ?

create a empty gameobject in your hierarchy and put this script on it.

yes i already done that , then i added this to a falling object:

function OnCollisionEnter(){

 ShowMessage("hit",2);

}

but get : Unknown Identifier ShowMessage

its working fine here... have put

function OnCollisionEnter(){

ShowMessage("hit",2); }

in the same script??? if not then working code will be -

 var showMsg = false;
 var msgText = "";
  
 function OnGUI()
 {
      if(showMsg)
      {
           GUI.Label(Rect(100,100,200,100),msgText);
      }
 }
  
 function ShowMessage(msg,duration)
 {
      showMsg = true;
      msgText = msg;
      yield WaitForSeconds (duration);
      showMsg = false;
 }
  
 // you can call ShowMessage() from anywhere you want, I have called on Start()
 function Start()
 {
     ShowMessage("This is your message",2);
 }
 
 function OnCollisionEnter(){
 
     ShowMessage("hit",2);
 }

you can paste my code where you have written your function OnCollisionEnter(), you don't need to find gameobject.
