The Jimmy Dean Show: Episode 324

Jimmy Dean explains that Rowlf is military minded, wanting to join the army. They cut to Rowlf at the fence, in a K-9 helmet toting an army rifle. He reassures America that he's on guard. Rowlf shares a letter saying they're delighted he's enlisting in the United States Army, signed the United States Navy.
Jimmy enters and tries to put Rowlf through some drilling and presenting arms. Rowlf just tosses the rifle to Jimmy, but he's planning to enlist as a sentry dog anyway. Jimmy reads a recruiting notice from the Air Force at Ridgeway, New Jersey (previously mentioned in the April 29, 1964 broadcast). Rowlf plans to avoid fighting by being with Intelligence (a sergeant said "Rowlf would be a lot better with intelligence.") Jimmy explains sentries mostly stop spies. Rowlf fires in advance ("Halt, who went there!") They try again, with Jimmy posing as the German-accented Rudolf the Saboteur. Rowlf lets him in. 
Third try, Jimmy tells him to wake up the camp (which Rowlf interprets as a summer camp). Rowlf barks but not loudly: "Bow Wow" (saying that's the bowest he can wow). Jimmy tells him to use a whistle instead, but the prop department failed to provide a whistle. One is handed to Jimmy ("Isn't that funny how it just came right up there.") So the spy approaches again. Rowlf exclaims, "A spy! Who came in from the cold!" Rowlf struggles to blow the whistle ("It's a wooden whistle, and it wouldn't whistle.") He keeps trying and slowly inflates, leading to the inevitable running gag: Rowlf's belly button blows out. Without a belly button, Rowlf knows the army won't take him, but Jimmy says at least he tried to enlist. They then sing "You're a Grand Old Flag."
