Skyrim Mer-der

Alright, listen up, buttercup. You see, the joke is a pun. "Mer" is a race of elves in Skyrim, and "-der" is from murder. Get it? It's like when you try to cook, and it ends up a "mess-terpiece" of burnt food. Hilarious, right? No? Well, stick to watching paint dry; it suits your intellectual speed.
