1.
An extremely funny theatre/musical performed by university students. Stories often relate to history and include jokes of other student organizations, celebrities, political figures etc. Frequently features crossdressing (due to lack of males/females contributing to the spex). The spex music is always provided by a live orchestra, all musicians are also students. The spex-tradition originates in Sweden, the first spex was performed in the year 1851 in Uppsala, Sweden. The oldest spex-tradition in Finland is carried out by Medicinarklubben Thorax (medical students at the university of Helsinki) who performed the first spex in 1952.
