edit: I got curious as to who that person is. I can't find ---steaming pile of meadow muffin--- about who or what episode it was on. In fact, I can't find anything more about just that image. Not even a Youtube video. But like you say, there are a shitload of posts about it.
I'm inclined to believe it's fake. A gaff that bad with what appears to be a set of screen shot would almost certainly make an appearance on Youtube.
