Power Puff Avengers brushing their teeth. Thor, why are you brushing Mjolnir?
…? Why, watever dost thou mean? I have no need of brushing my teeth- Mjolnir, however, lacks the ability to cleanse herself therefore I must do so.
Is this practice uncommon?
*facepalms* It’s called a toothbrush for a reason. You can get a cloth to wash the stupid hammer.
*gets defensive* Mjolnir is not one without a brain, dear friend! Need I remind you she was forged in the heart of a dying star by my very own people- something you Midgardians have yet to even begin to understand?
