The origins of the activity dates back to the 1952 playoffs when a National Hockey League team played two best-of-seven series to capture the Stanley Cup.
The tradition started on April 15, 1952, when Pete and Jerry Cusimano, brothers and storeowners in Detroit's Eastern Market, hurled an octopus into the rink of Olympia Stadium.

[4] On October 4, 1987, the last day of the regular Major League Baseball season, an octopus was thrown on the field in the top of the seventh inning at Tiger Stadium in Detroit as the Tigers defeated the Toronto Blue Jays, 1–0, clinching the American League East division championship.
When the Red Wings played at Joe Louis Arena, he was known to twirl an octopus above his head as he walked across the ice rink to the Zamboni entrance.
In an email to the Detroit Free Press, NHL spokesman Frank Brown justified the ban because matter flew off the octopus and got on the ice when Sobotka swung it above his head.
