Types

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
A freak show, also known as a creep show, is an exhibition of biological rarities, referred to in popular culture as "freaks of nature". Typical features would be physically unusual humans, such as those uncommonly large or small, those with ...
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, like
Isaac W. Sprague). 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.

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 described provocatively, often as something deemed too strong for women and children, such as

*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 Drug 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 th
