I understand that very few of you are going to get this, so here goes:
Metalocalypse is a cartoon about a death metal band named Dethklok. In episode 13, the lead singer, Nathan Explosion, has a dream that the rest of his band is pecked to death by birds. Because he is too stupid to do anything else, Nathan is forced to go to work at a fast food restaurant.
The restaurant is called Dimmu Burger.
Dimmu Borgir is a melodic black metal band from Norway.
I really have no use for Dimmu Borgir, but I found it funny enough to throw the logo together to put on a T-shirt.
I also included a copy in scalable vector graphics (SVG) format (right click, Save As…) for resizing in your favorite art program for those so inclined.
