It’s the YouTube channel Mental Floss’s birthday, and to celebrate, they’ve compiled a list of birthday traditions from all over the world. While in retrospect it’s obvious, the thing that surprised me most about this video was the realization that people haven’t always celebrated birthdays, and that it’s not a tradition held across all cultures. I suppose I just can’t imagine a world where my family and friends don’t shower me with cake, love, and presents on at least an annual basis.

Anyway, there are some great and strange traditions in here, and you should give them a try. The most inexplicable to me comes from Canada, of all places: spreading butter on the nose of the birthday boy or girl. If any Canadians out there know where this tradition came from and want to explain it in the comments, please do.
