Detroit News, 1931. This is satirical comment on crooners like Rudy Vallee and Bing Crosby, whose intimate new vocal style was made possible by the invention of the microphone. Like all things related to jazz, crooning was widely seen as a terrible source of cultural pollution.
I sort of love how labored this kind of humor is. By the time we get to the punchline, the dead-horse set-up has not just been whipped but pureed into equine guacamole. And the repetitive image of the straight man shielding his eyes against the brilliance of the singer’s diamond tie pin is so dumb it’s genius.
