Y'know what, i'm not gonna give the copy paste answer where I tell you to watch it yourself.
It's the goddamn greatest thing since sliced bread. You like animation? Well Friendship is Magic invented animation, you're welcome. Ponies cure cancer and split the atom, Rainbow Dash is 20% cooler than Jesus piloting Voltron, there is no God there is Princess Celestia, Fluttershy is the reason the word kawii exists, if you watch it it'll cure your AIDS as well as bring your dead goldfish back to life, and friendship is mother fuckin' magic.
