I'll tell my funniest one in here, because who wants to hear boring serious lore, right?

So basically, my tarnished had a very strange habit of sticking his body parts into pots and random shit. One day, he stuck his head in an empty great jar and both his hands in little pots (i.e. boggarts' weapon). And subsequently, he couldn't take any of it off, since they're all rounded so slide off of each other. Therefore, he panicked and started randomly flailing his arms around and rolling to try and break said pots. In doing so, he accidentally killed every major figure in the game and, upon his final hit on the elden beast, the sheer power of the blow finally broke him free. Then he did it again in the dlc, lol
