before the mannequin challenge, planking, or the Harlem Shake, the hot meme of 1959 involved teenagers cramming as many of themselves as possible into a phone booth

I’m guessing this fad happened because streetcorner phone booths had just become commonplace. Before that they were only inside stores and restaurants, and probably supervised by the staff.
