yes, when these teams have met there has always been an exuberant student rivalry. It seems to add some fun to the hockey drudgery.
I have seen the flying fish,octupi thrown on the ice similar to the Detroit Red wings display a few years ago.
Donuts,bagels, blow up dolls,dead fish etc etc. Some parents and faculty go crazy with vengence and others who understand the hockey world take it in stride as fun for the players and rivalry. This occasional display has been done only in fun. Amazing to see the entire student body at Wisconsin D-1 games yell chants to othwer teams during a game.
Hopefully, the female students will not have enough time to prepare their arsenals
