The Unbearable Lightness of Being -- gay. While the clips & pics of Bert & Ernie acting gay are funny, know what really fascinated me in the OP clip?
The table radio! The brown & beige boxy thing in the background, with the round tuning dial and the heavy egg crate speaker grill.
My parents had that exact same radio on a bedroom night table when I was growing up. A product of the late1940s, the dial & pointer evoked the outdated Deco style, while the case was a precursor of the more severe 1950s rectangularity to come.
Since my parents didn't allow me a bedroom radio of my own when I was a pre-schooler, as a special treat they'd sometimes let me fall asleep in their bed, listening to that radio. In the early '50s, it was still possible to hear radio comedy shows with live audiences, starring the likes of Bob Hope, even while he and other radio entertainers were simultaneously transitioning to TV.
I wonder if focusing on the style of an old radio is more gay than speculating about the sexuality of a pair of puppets?
