Well, I was only pointing them out specifically as two of the least important supporting cast members. Off the top of my head, we've seen of the recurring variety: John Lithgow Rachel Bilson Danica McKellar Bill Fagerbakke Wayne Brady Sarah Chalke Laura Prepon And the guy who plays Ranjit. And I'm sure I'm forgetting some. These all appeared in at least two episodes, most in many more. And none of these were "stunt-casting" (like Britney Spears was).
