The Order of the Stick: Battle for the Gate|
The Order of the Stick is my favorite webcomic. It's based on Dungeons & Dragons, though you don't have to know anything about D&D to enjoy the comic.
To show you how awesome OotS is, I thought I'd share this extended sequence.
Y'all really should check out The Order of the Stick if you haven't already.
