In the 1950's, the University of Michigan public-address announcer, Steve Filipiak, began a tradition of giving Slippery Rock scores. While calling Michigan games from the box, he started reporting the scores from around the country, and particularly those from that funny-named school in Western Pennsylvania, Slippery Rock. He continued this until his retirement in 1971. The tradition of reporting the Slippery Rock scores stuck, and in fact was a veritable cult classic around the nation.
