In America, a sideshow is an extra, secondary production associated with a circus, carnival, fair or other such attraction.

Types of attractions

There are four main types of classic sideshow attractions:

•  The "Ten-in-One" offers a program of ten sequential acts under one tent for a single admission price. The ten-in-one might be partly a freak show exhibiting "human oddities" (including "born freaks" such as midgets, giants or persons with other deformities, or "made freaks" like tattooed people, fat people or "human skeletons"- extremely thin men often "married" to the fat lady). However, for variety's sake, the acts in a ten-in-one would also include "working acts" who would perform magic tricks or daredevil stunts. In addition, the freak show performers might also perform acts or stunts, and would often sell souvenirs like "giant's rings" or "pitch cards" with their photos and life stories. The ten-in-one would often end in a "blowoff" or "ding," an extra act not advertised on the outside, which could be viewed for an additional fee. The blowoff act would be deas pickled punks.
• The "Single-O" is a single attraction, for example a single curiosity like the "Bonnie and Clyde Death Car" or Hitler's staff car, a "Giant Rat" (actually usually a nutria) or other unusual animal, a "What Is It?" (often a convincing but artificial monstrosity like the Fiji Mermaid) or a geek show often billed as "See the Victim of Drugscribed provocatively, often as something deemed too strong for women and children, such  Abuse."
• A "Museum Show" which might be deceptively billed as "World's Greatest Freaks Past and Present," is a sideshow in which the exhibits are usually not alive. It might include tanks of piranhas or cages with unusual animals, stuffed freak animals or other exotic items like the weapons or cars allegedly used by famous murderers. Some of the exhibits might even be dummies or photographs of the billed attractions. It could still be truthfully billed with the claim "$1,000 reward if not absolutely real — please do not touch or feed the animals on exhibit". The Single-O and the Museum Show are usually operated as "grind shows," meaning that patrons may enter at any time, viewing the various exhibits at their leisure.
• A "Girl Show" was sometimes offered in which women were the primary attraction. These could range from the revue (such as a "Broadway Revue") with fully clothed performers to the racier "kootch" or "hootchie-kootchie" show (a strip show) which might play either partly clothed or "strong" (nude).

Sideshow arts

"Working acts" often exhibited a number of stunts that could be counted on to draw crowds. These stunts used little-known methods and offered the elements of danger and excitement. Although the mainstream media often explained fanciful methods of performing these acts, the real secret was usually that there is no secret, you just do it. Such acts included fire eating, sword swallowing, knife throwing, body piercing, lying on a bed of nails, walking up a ladder of sharp swords, and more. The renewed attention to these feats has prompted a new round of oversimplified or inaccurate explanations, leading some inexperienced people to attempt them without adequate training often resulting in injury and sometimes even death.
