No recorded history of someone dropping the Stanley Cup 'on the ice after winning it' but it has took a tumble and has fallen many times during celebrations of the victors.
In 2011, the Stanley Cup took a tumble when Former Boston Bruins' Michael Ryder brought it home to Bonavista, Newfoundland.
It reportedly took a tumble as well during the Red Wings' celebrations in Detroit in 2008 after some players took the trophy to Cheli's Chili Bar.
The Stanley Cup's original name is Dominion Hockey Challenge Cup. The silver behemoth is the oldest trophy awarded each year to the winner of the playoffs held between the teams of the National Hockey League. The cup's history is rich and is continually being embellished because each year, members of the winning team are allowed to take the Cup home with them.
It regularly hits the road with the very lads who won possession of it and it is that life outside the trophy case that has given the Cup a lively history. Each winning player and team management member gets to take the Cup home to share it with family and friends for a day or two. It is on tour approximately 250 days a year.
The Cup is always accompanied by at least one representative of the Hockey Hall of Fame, dubbed the “Keeper of the Cup.” The current Keeper, Philip Pritchard, has held the position since 1991 and even maintains a Twitter account to update followers on where the Cup goes from day to day.
