Years ago a group I mastered aquired a castle but wanted to leave it for a few days withoug leaving someone behind. The gnome-rogue, not completly healed locked the door from within and wanted to climb the wall to get out. he botched his first roll and fell down, dying from the impact. The first reaction of one of the other players was to look at his character sheet and mentioning: "Well, probably my ring of featherfalling would have helped there."
Probably not very funny when you weren't there (or if you were the player of the gnome).
