This episode features a character, the Simpsons’ family dentist, Dr. Wolfe. Dr. Wolfe was supposed to be a celebrity guest voice. Both Anthony Hopkins and Clint Eastwood turned down the role. Tony “Norman Bates” Perkins did take the role, but died before he could record it, so regular cast member Hank Azaria ended up doing it.
They also originally approached O.J. Simpson for the news panel show, but he declined. People were kinda happy about that. You know why. Dr. Joyce Brothers got the line instead.
