I found it humorous in the books, but not like this. It may sound incredibly petty, but I find that it's just sad that these keep making the front page. As far as I can tell, these are just copyrighted quotes written in a downloaded font on a coloured background.
I loved this. So much bromance for Harry and Ron, making up a thousand different ways how they could get hurt or die. Very funny, too. I missed these magic moments in the movies. I loved the third movie, though.
