It’s been running for some time now, and I don’t generally enjoy sprite/photo/screencap comics of this style, but DM of the Rings has been consistently amusing me, at least for the first twenty-three comics. I know my RP’er friends and I always make these jokes MST3K-style while watching LOTR (and my mind is always calculating the D&D rolls used in/needed for each scene regardless of who I’m with).
Update: Okay, I’ve finished reading the archives, and I still love it! Go! Read it now!
