I DISBELIEVE! *THUD*
So, here's the story, back from the olden days of D&D (back in high school). We had your typical party, I think. Ranger, rogue, monk, paladin, wizard and necromancer (keep in mind, this from from before I joined the group). Now, the party was traveling along, when suddenly they opened a door and saw a brick wall directly behind it.
Here's what this actually meant: The DM told me after the event that somehow, in the process of drawing the map of the dungeon, he'd forgotten to put a room behind this door and didn't realize it until that moment. Rather than trying to come up with a room on the fly (which rarely turns out well), he put a wall there.
What the necromancer thought this meant: It was an illusionary wall. He dropped his head and charged at the wall shouting "I DISBELIEVE". He took a d6 of damage (at first level), lost a point of Intelligence and was knocked out for a few hours.
Haw.
