That's kind of self-contradicting sentence. Yet it still answers the question. I have to agree with you. And the fact the votes have dispersed among the pictures like they have further proves the point: Different people find different things funny.

Although in a certain sense I still think that maybe having all the groups have the same picture might have also worked. It would have been a more true competition. Now it's just not choosing between the subtitles but also choosing between the pictures, and the teams couldn't affect that at all.
