With old tricky dicky being a hot topic right now, I've had the dubious delight of explaining a few times that they haven't found his 'tomb', they won't have found him laid out in crown, weapons, armour, robes... (badge saying "Hello I'm Richard III, How may I slaughter you?") and they may never be quite able to pull off the DNA tests as they can sometimes be difficult to pin down with certainty.
For some reason, explaining this disappoints people.
