Bob Gassoff.
Gassoff played for the Blues against the Habs in the 1977 Stanley Cup quarterfinals shortly before he died, (I lived in Montreal at the time). When he was on the ice, he'd hit any Canadien he could, regardless of whether or not they had the puck, and kept doing it until he was assessed a minor penalty for something. He had ten penalty minutes in the series, and probably two minutes of ice time. The Habs scored multiple power play goals while he was in the box. We considered him a joke.
