Humorology, or "Humo" for short, is an annual musical/variety show show that takes place at the Union Theater of the University of Wisconsin-Maison campus. The final performance consists of six original mini musical comedies that are entirely written, produced and performed by six independent companies and overseen by a student run executive board. It is also a judged competition. Having started in 1948, Humorology is one of the oldest traditions at the UW Madison and has become the largest non-profit student service organization in Wisconsin.
