Sideshows are an extra, secondary production associated with a circus, carnival, fair or other such attraction.
The "Ten-in-One" sideshow 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 or fat people.) 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 described provocatively, often as something deemed too strong for women and children, such as pickled punks.
