This thread has been revealed to regular users so people have an easier time to find suggestions that has been posted before. Do not post "this thread already exists" or link to this thread in any thread anywhere on this board. That counts as backseat moderation, and if i see anyone posting something like that i will do my very best to get him infracted, and certainly warned.
That said, please check this thread before you make a suggestion. It's more of a dump for the worst mergepastas, so most merged threads won't go here.
