Let's never forget the time my players found a very old grave that had the words "Here Lies Asmodeus" on it and dug it up.
Their justification was that of course it's not actually him, and the rogue wanted to rob a grave.
To clarify: it was him. He'd been sealed there by a famous monster hunter and was gonna be part of a later plot.
I will forever love that of all the moments in any of my games, this is the most known.
Quick update: I misremembered, it was in fact the paladin who dug him up.
