When Roger Healy comes in and greets Tony Nelson, Jeannie pops in between them and mistakenly says "Hello Captain Healy", referring to Roger as "Captain" after both Roger and Tony had been promoted to "Major" 2 episodes before in "How Lucky Can You Get?"
Dr. Bellows tells Gen. Peterson about the elephant and says, "His name is Tiger," and he mentions it again in Tony's house ("You called him Tiger."). But Tony never mentioned that to Dr. Bellows. Tony told Jeannie about a poodle he had when he was a kid and the poodle's name was Tiger.
