I had an "emergency" button order so I didn't have time to read a manga today. So instead I'm going to share a funny webcomic link I came across a couple days ago.

It's called "DM of the Rings" and here is the premise from the site itself:
Lord of the Rings is more or less the foundation of modern D&D. The latter rose from the former, although the two are now so estranged that to reunite them would be an act of savage madness. Imagine a gaggle of modern hack-n-slash roleplayers who had somehow never been exposed to the original Tolkien mythos, and then imagine taking those players and trying to introduce them to Tolkien via a D&D campaign.
It's a webcomic, made with screen caps from Peter Jackson's LoTR trilogy, that ran from September 2006 to September 2007. In that time the creator Shamus pokes, prods and shamelessly rips into every tabletop gaming joke and exposes every plot hole in the LoTR trilogy. If you've ever played D&D, or known someone who has, or happened to hear someone talking about gaming, you'll find this funny.
There are so many things that are annoying about table top roleplaying. The endless math, the people not paying attention to the DM, the DM putting the story on rails and not letting you off, people not staying in character, people staying too much in character...
Some how it's a lot funnier when it's Aragorn and Legolas fighting over who gets the loot or Dave, er, Frodo deciding he'd much rather be a Jedi then a Hobbit.
My main recommendation for reading this comic is to make sure to read the author's "DM notes" at the bottom of each comic. They're hilarious and on point. Then read the comments by the readers. They start off laughing along and then devolve into incredible geekiness that is sometimes funnier then the comic itself (and the comic is pretty darn funny.
