Wikipedia describes the meaning of Labour Day as:
It goes on to describe the differences between our countries and so on... what a load of crap.
I'm here to tell you the true origin of Labour Day.
It was a French holiday celebrating beer. That's right... La Beer Day.
It was a heavily celebrated holiday with much love shown for this amazing beverage. As a result, speech slurred and eventually transformed it into what we know today as "Labour Day".
I shit you not. Don't let anyone tell you different. Why else would there be line-ups at beer stores on the Friday before the weekend?
Have an awesome La Beer Day weekend, have fun, and play safe. :)
