>>157888They get their name from this guy, Tony Kornheiser. This was the original one, and the first derivatives of it were other images of Kornheiser but with different words underneath for different occasions. The thing that makes Kornheiser images special is the word/text is actually from the same image as his face, they just cropped the word/text, blew it up, and then cropped the image to nothing but his face and stuck the text under it. All the copies also follow this same method.
It works really well with anime because of subtitles, so you often have people making funny faces with text below them that can be easily blown up and cropped.
