A couple of (I think dungeons and Dragons related, but definitely table RPG related) funny bits.
DM of the rings. NoahFence posted these at INTPcentral (Warning, they take a long time to read completely through.). although based on tabletop RPG games, there is plenty resembling computer RPG games, and probably stuff that anyone will find funny.
The Tale of Eric and the Dread Gazebo [rec.humor.funny], this is a short joke.
