Jack, Jeff, and Steve Hanson are the three bespectacled bloodthirsty and dimwitted hosers who are hired for bottom dollar to play hockey for the Charlestown Chiefs in the movie Slap Shot. The three brothers accumulate quite a number of fans by acting like complete hooligans and beating everybody up including the referees and the crowd.
They speak with heavy rural Canadian accents and are dumber than a box of rocks, but they do end up drawing a crowd, and in some sense they save the day. In some ways they are a caricature of the hockey goon that many americans think of when they think about hockey, although since the movie was made in 1977 many more americans understand and enjoy hockey.
