Those of you who are loyal listeners to Dinner and a Podcast know that Steve was discussing the Stanley Cup Finals between the Pittsburgh Penguins and the Nashville Predators, and how they are IDing people in Pittsburgh who want to buy whole catfish. The guys wanted to know why the tradition started for Nashville and why Red Wings fan throw octopi on the ice. This traditions are loosely linked.
The catfish in Nashville has a less fabled story of origin, but is more symbolic of the region than octopus and Detroit.
The first throwing of the catfish happened at a game between the Red Wings and Predators in response to the Red Wings throwing an octopus on the ice. In 2008 during the playoffs between the 2, 4 catfish were tossed to the ice. More recently a Nashville fan snuck a catfish into the Finals and threw it on the ice in Pittsburgh. He was promptly escorted out and arrested (http://deadspin.com/preds-fan-who-threw-catfish-on-the-ice-charged-with-pos-1795654574).
