Old Birdman is sinning CinemaSins' Harry Potter 1 video.
Enjoy!
(Note: I am aware the comments keep winding up disabled. I believe this is a bug on YouTube's part, and I have no control over this. I keep enabling them, and they keep getting disabled)
Disclaimer: I actually REALLY enjoy CinemaSins, and am only making fun of them here. I do not hate them, nor am I a "hater". This video is all in good fun.
