In the sport of hockey, the goaltender is a unique position, requiring such a particular set of skills that a team cannot just substitute another player at the net. Teams keep two goalies ready, and also a designated emergency backup, an experienced amateur, on the off chance that their two goaltenders are injured. Saturday night, the Carolina Hurricanes saw both their goalies injured, and called up 42-year-old Zamboni driver David Ayres to fill in. He made eight saves on ten shots to help the team defeat the Toronto Maple Leafs. A good time was had by all. -via reddit
