History: Freaks Of Nature

Freak shows were popular in the United States from around 1840 to the 1970s, and were ten, but not always, associated with circuses and carnivals. Some shows also exhibited deformed animals (such as two-headed cows, one-eyed pigs, and four-horned goats) and famous hoaxes, or simply "science gone wrong" exhibits (such as deformed babies).
Changes in popular culture and entertainment led to the decline the freak show as a form entertainment. As previously mysterious anomalies were scientifically explained as genetic mutations or diseases, freaks became the objects sympathy rather than fear or disdain.
Today, Michigan law forbids the "exhibition any deformed human being or human monstrosity, except as used for scientific purposes". However, in many states in the USA and in other countries abroad, one can still see freak shows at carnivals and state fairs, in bars and nightclubs, and on daytime television talk shows.
