I came across "DM of the Rings" on Neatorama the other day and had to read all 155 installments. It's a hilarious web comic by Shamus Young that uses scenes from the Peter Jackson Lord of the Ring movies to imagine a group of Dungeons & Dragons players reenacting the Lord of the Rings. Needless to say the players haven't read the book (or seen the movies), and while D&D is a role-playing game, the players have a hard time staying in character.
The first episode is a good place to start. As a science geek, I particularly liked Schrödinger’s Familiar. If you aren't familiar with the gazillion monsters character might run into, a Lich is a sort of undead sorcerer.
