When does a squid get thrown onto the ice at a hockey game?

Back in the '50's, a local seafood shop owner decided to throw an octopus on the ice during a Red Wings playoff game in order to bring them good luck. Back then, only 8 wins were needed in the postseason to win the Stanley Cup, and so the octopus' 8 tentacles represented the number of games Detroit had to win. Detroit went on to win 3 consecutive Stanley Cups in the '50's and the local seafood shop owner was hailed as a hero.
