I was making fun of those jerseys last night to a guy I play hockey with who is from Montreal. It was obvious that he is a Habs fan when he was wearing a Habs hat, jacket, and his hockey bag was in Canadiens colors.

I did NOT use Gresch's line about a gay French prison so as to avoid fisticuffs but boy was I tempted.
He told me they are from 1914 and the CAC stands for "Club Athletique Canadien". There's some useless trivia for you.
