The secret word in this episode is "go" which is said and barked at twelve times. However, nobody barks when Randy tells the Magic Screen, "I'll go crazy in here!" while in his prison cell, when Dr. Jinga-Janga says, "Go right ahead" over the Picture Phone, or when anybody says the present participle going or the past tense went.
Randy obtains the secret word in this episode. Also, instead of letting them scream at it, this is the only episode where everyone barks like a dog when the secret word is said aloud.
