Once in my early days, I ran a game where the players were all werewolves. I was reading a lot of GRM at the time and it was very edgy and I tried to give them a moral quandary: an injured baby. Do they curse the child with lycanthropy to save it?
That's when the players hauled out the cursed healing potion from 15 sessions ago they'd been hauling around this whole time :/
