Close, Puffy. Some time back I downloaded all of the scripts and I just searched them. According to the script, Dr. *Peterson* Klein appears in "Don't Tug on Superman's Cape," two episodes earlier. This Dr. Klein was played by the same actor as Bernie; I'm not sure what first name was used in the actual DToSC episode, but I am guessing it is meant to be the same character.
Joy,
Lynn
