I disagree with you, I think it's perfectly suitable for this gallery. If you look at the vibrating gifs gallery none of them have any kind of caption, including those linked with expand dong. If you have to pointlessly shunt them into another gallery then you can atleast move my other one as well rather than singling this out.

In my opinion, all this X% MAD business needs it's own meme or something, instead of putting it in vibrating gifs. I fell like it's becoming quite common.
