The Joker had run out of toilet paper, and was currently stealing roll by roll out of your TP holder. You just watched, dumbfounded. Suddenly, a hole was burst into your wall, and Batman stepped through, not even caring to assess the damage. He grabbed ahold of The Joker, and then realized what he’s done. He placed a single square of toilet paper down, it now resting on the smashed drywall. He pat it, and made his leave, not bothering to look at you.
