Now this is something we don't see everyday... 

A Swedish hockey ref choked a player and made him tap out, after the player took the referee to the ice.  

In a game between Vaxjo and Färjestad of the Swedish hockey league, a traditional hockey scrum started in the beginning of the third period.  The referee got in the middle of the fight, and was taken to the ice.  Fed up, he pulled the hockey player out towards the middle of the ice by his neck, and forced him to tap out.
