Last year, Molson put a refrigerator full of beer in an English square that would only open if you had a Canadian passport. That made the first Canadian to show up into an instant hero! The beer company has taken that stunt one step further with a refrigerator that will only open if you can sing the Canadian national anthem “O Canada.” Since our neighbors to the north are feeling particularly patriotic today, this is a good time to hand out beer to those who know their anthem. Happy Canada Day! -via mental_floss
