Yeah, I'd really prefer we didn't have an actual thread for this. I think that 99% of those posters are stupid. Like the one above, for example. A few are great and hilarious and what have you, but they're really not worth the bucketloads of junk you have to sift through.
I will also note that this would not be the correct subforum for such a thread. It would belong in the Media & Inspiration forum, since its not actually directly about RPGs, its rpg-related media.
