Goose Day. Happy Goose Day actually. Pretty fun name for an over 1,500-year-old holiday, according to Penn Live. If you didn't celebrate this little-known holiday on Sept. 29, look no further; the history of Happy Goose Day will be revealed and you will be ready next time.

Happy Goose Day traces its roots to the year 480 and is sometimes called Michaelmas Day. It was created by Pope Felix III as a celebration for the Archangel Michael.

Fast forward to the 15th century and Michaelmas gets a new purpose; it is a day when people paid their rent to the landowners. Oftentimes this was done with a goose (see where we are getting it now?), and if you were fortunate enough to pay your rent with a big plump goose that you got your hands on, your lease was renewed another year. (Poor goose.)

And so the holiday is about eating a goose, according to the Examiner, which hardly seems to make for a happy goose day... for the goose that is. So, while we are not advocating a meal of goose, do recognize these funny birds today and smile at their changed fortune that it is no longer medieval times and goose fattening times.

There seems to be two kinds of geese in these world: sweet and sour. The sweet ones follow people and eat bread from your hands at the duck ponds. Some even fly alongside a car as we have seen in videos, including this one here.

But then there is always that rogue street goose - the one who loves to chase and frighten a person, just for kicks. It keeps his street cred up. He's bad; bad to the bone. This video clip here shows a bad goose, which for whatever reason had it in for this guy. Maybe he had it coming? Maybe he is just showing off for his friends. Either way, what a relentless little guy. Enjoy!
