If you are not familiar with the Brony phenomenon then you really need to do some research. Long story short…Bronies are the newfangled fandom (made up of an inordinate number of dudes) of the revived My Little Pony cartoon franchise. They have conventions and do cosplay and are just as rabid about My Little Pony as the most diehard Trekker is about Star Trek.
And if you follow the jump, you will see that they also party hard as a mofo.
That stirring rendition of Twinkle Twinkle Little Star was something else.
