Other performing societies include the Gilbert and Sullivan Society, PantSoc who stage a student-written pantomime three times a year, and York ComedySoc, one of the most active comedy societies in the UK, putting on a show every week along with workshops in stand-up, improv and sketch writing/acting. ComedySoc sends two shows to the Edinburgh Fringe each year: The Shambles, ComedySoc's in-house improv comedy troupe and The Dead Ducks, ComedySoc's in-house sketch comedy troupe. Both troupes perform throughout the year on campus and in/around York and have received critical acclaim for their shows at the Edinburgh Fringe.
