This is a cool Grantland "30 for 30" short about 70's Bruins tough guy John Wensink. He briefly describes what I guess could be the hockey player's version of the "exam dream".

His last NHL game was in 1983 (for the Devils). Very loosely paraphrasing... "I still occasionally have this dream where I get a call up from the Bruins and I can't get my skates tied up and they leave me behind".
