Switch statement in If in GUI function

For learning purposes, I'm basically making a Taboo game version, I have a OnGUI function, with a if statement and a switch statement inside.

I have this code with a few Debug.Log to test it, everything works just except for the GUI.Label's showing up as supposed.` function OnGUI() {

 GUI.Box(Rect(24, 29, 332, 372), "", boxStyle);
 if(GUI.Button(new Rect(22,401, 50, 50),"Pass"))
 {
     Debug.Log("Test");
     var randomWord = Random.Range(0, wordHeader.length);   
     var word = wordHeader[randomWord];
     Debug.Log(word);
     switch(word)
     {
         case "Carrot":
             Debug.Log("c"); 
              GUI.Label(Rect(0,38,Screen.width,Screen.height),"Carrot", labelStyle);
              GUI.Label(Rect(0,160,Screen.width,Screen.height),"Orange", badWordsStyle);
              GUI.Label(Rect(0,220,Screen.width,Screen.height),"Vegetable", badWordsStyle);
              GUI.Label(Rect(0,280,Screen.width,Screen.height),"Bunny", badWordsStyle);
              GUI.Label(Rect(0,340,Screen.width,Screen.height),"Crunchy", badWordsStyle);        
             break;'

However without the If statement, it seems to loop through the array every frame instead of just once, I think I have a solution for this part, but I can't figure out how to get the GUI.Label's to show with the if statement in place, all the Debug.Log's work fine, thanks in advance, any questions I'll be glad to answer
