THIS DATE IN HISTORY: April 15:
1952: The tradition of throwing an octopus onto the ice begins when the Detroit Red Wings become the first team to win the Stanley Cup without losing a playoff game by defeating the Montreal Canadiens 3-0 in Game 4 of the Final.
Metro Prystai scores two goals and Terry Sawchuk earns his fifth career postseason shutout, helping the Red Wings finish 8-0 in the 1952 playoffs.
Brothers Pete and Jerry Cusimano, store owners in Detroit's Eastern Market, make history when they toss an octopus onto the ice at Olympia Stadium. Each tentacle symbolizes one of the eight victories needed to win the Cup during the Original Six era.
