I don’t have any stickers on my car, but I would so have a sticker made of this.

Just for the one, maybe two times some one might ask about it, and explain that “I like the art work of Masamune Shirow”
“Who”
“You know,Ghost in the Shell?”
And then watch the look of pain on their face as they have to process that pun.

Something tells me this would have a long payback period.
