Have you watched anything else Baka Test like the 2nd season, OVAs, and specials? And hm, I think I remember it being possible, or at least it's possible to vandalize the tags on it, I've been to sites where it specifically warned me about using tinypic when I tried to post link there. Although I see that you already very rapidly moved it to imgur, so I guess it's all good now regardless.
Vandalize tinypic links? I haven't heard of this. It's a really old gif I spotted in one of my old posts that I decided to grab for nostalgia lol.
