Late February of '10 is when I first was made aware of it. I've been an off and on [rule1] lurker for a while, And in mid Feb decided to be on again. I really didn't know what to make of the images of colorful horses being spammed around when I saw them. After a few days I found out about the new MLP website hasbro was setting up, and lol'd at it. then I made my fatal mistake. I played that personality game. [Ended up as twilight, like a baws]. I decided what the hay, I'd watch an episode and see just what people liked about it. Next thing I know its 4 in the morning, and I'm up to about episode 8 or so realizing I need to sleep for work in the morning.
And thats the story of how Pinkie Pie got her cutie mark
