Dennis loves the sport of hockey ad thinks that hockey players are some of the toughest out of any sport. Apparently some of them, specifically Maple Leafs goalie James Bernier, isn't necessarily the smartest. A reporter asked Bernier a question about Nelson Mandela, who Bernier referred to as "one of the most known athletes in the world," while at the Toronto Raptors' Giants of Africa event. Apparently Bernier isn't quite up on his current events.
