What would be the infringement? I would say any animated GIF (or whatever) should be defined as fair use across the board, since it's impossible to use it for anything other than criticism or comment. It's not exactly like Beastie Boys vs. Chambers Bros, but it rhymes with it.

Isn’t there a gif of the entire first Shrek movie?

Perhaps, but that's clearly not covered by fair use. Posting the entire Shrek movie as a GIF is not creating a "new meme".

a heavily accelerated 49px by 49px gif seems okay
