I think other people are being overly critical here. It's short, yes. But it's long enough to play out the joke and that's all it needs to do. I think that's exactly how Derpy would play the piano. Excellent flash.
Friggin retarded ponies.
Well its official. Retarded ponies DO make everything better. You made my day. Great job.
I love Derpy!
