The Bizarre College Craze of 1939
In the late 1930s, American college students sparked a nationwide trend by swallowing live goldfish. This strange test of bravado became a viral sensation that swept across campuses before abruptly fading away.
It all started in 1939 when a Harvard freshman swallowed a fish on a dare, igniting a competitive frenzy among peers. Soon, students everywhere were gulping down live goldfish to prove their social status and toughness. Some individuals even managed to consume dozens of fish in a single sitting. The fad eventually lost steam as animal welfare concerns grew and public interest shifted toward other activities.
