J'ai fini Sanitarium il y a trois minutes, et yavait tellement de complots contre moi là-dedans que je vais sûrement en garder un complexe de persécution.

In that same Sanitarium game, I had the surprise of my life when I heard the children sing a song I read in some American book a while ago, can't remember the beginning, something about "posy" and "ring around a rosy" (or something) and it ends with "ashes, ashes / we all fall down".
The scary part is that, if I remember well, that song refers to the... black plague ? something else ? anyways, something of that kind, it was pretty scary to get those children holding hands, circling a human skull standing on a giant eye singing that song !
