Burns and Allen radio show 1/15/45 Alan Ladd Making George Jealous 

George and Gracie go to see an Alan Ladd movie, and Gracie is smitten. When this makes George jealous, Ladd shows up in person.
George makes a reference during the movie to Vox Pop, which was a popular radio show with man-in-the-street interviews and quizzes. The title comes from the latin phrase "vox populi". Mel Blanc's downcast mailman makes another appearance; the character was a takeoff on Bill Thompson's Wallace Whimple character from Fibber McGee and Molly.
This episode starts with a wartime plea from Gracie to conserve paper. Even toward the end of the war, there was a strong focus on conservation and the homefront war effort
