What is "humorology"

Humorology, or "Humo" for short, is an annual juried musical/variety show that takes place at the Union Theater of the University of Wisconsin–Madison. The competition consists of six original mini musical comedies written, produced and performed by independent companies and overseen by a student-run executive board. Begun, 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.
