Max switches the radio on for the morning news read by the anonymous "McMillan voice" [Episode #92: "The Worst Best Man"].

Numerous episodes of Get Smart's third and fourth seasons feature the same anonymous male voice portraying off-camera roles such as airport announcer [Episodes #65: "Maxwell Smart, Private Eye" and #89: "Closely Watched Planes"] and radio newsreader [Episodes #90: ""The Secret of Sam Vittorio" and #92: "The Worst Best Man"].

Some of the more noteworthy appearances are as "McMillan" (hence the designation) in Episode #88: "Snoopy Smart vs. the Red Baron", a voice-over mimicking Arte Johnson's Laugh-In catchphrase "Very Interesting" while Starker lurks behind a bush on Schwartz's Island [Episode #99: "Schwartz's Island"] and the voice of ARDVARC in Episode #109: "Leadside".
