Proof of Harley's Wrongdoing!

Many times, Harley acts like he is innocent even when he is being bad. When my Mommeh tries to take video of him, he stops acting bad! I guess he does not want his bad behavior captured on video.
But I finally have PROOF! I don't think Harley realized the camera was behind him. I was just relaxing in the sink and the Harleymaniac went and... MANIAC-ed!
If you can't see the video here, you can watch full-sized on YouTube!
