Among the stranger traditions in college hockey is that when Dartmouth scores their first goal of the game against Princeton, students throw tennis balls on the ice.
The tradition dates back to 1998 when a single Princeton student threw a tennis ball at a Dartmouth goalie after Princeton's first goal of the game. Since then, Dartmouth has retaliated by throwing hundreds of tennis balls onto the ice:
It's mostly a fun tradition that results in the occasional delay of game penalty. But this weekend, Dartmouth hosts Princeton in the first round of the ECAC playoffs.
