Premise: A taxi dancer is a paid dance partner in a partner dance. Taxi dancers are hired to dance with their customers on a dance-by-dance basis. When taxi dancing first appeared in taxi-dance halls during early 20th-century America, male patrons would buy dance tickets for ten cents each.
Hypothesis: A taxi dancer is a paid dance partner that was invented by aliens from the future to control the minds of male patrons in the 20th-century.
