Archie predicts disaster when Mike and Lionel participate in an anti-Pentagon demonstration at the U.N. building. It turns out that Archie is right -- but disaster befalls him, when, showing up at the demonstration to take Mike and Lionel home, he ends up in the slammer himself. Allan Melvin appears as Desk Sergeant Pulaski, and it's too bad that Archie doesn't know the good sergeant's last name before he shoots off his mouth in the final scene. Scripted by Paul Wayne, Michael Ross, and Bernie West from a story by Wayne, "Archie In the Lock-Up" originally aired on October 2, 1971. ~ Hal Erickson, Rovi
