I do know a bit about Bun-bun, I just couldn't remember Bun-bun's current parental status.
Good point about the audio-- I almost never have the audio on, especially at the office. Perhaps I should re-watch--and listen to-- the video.
But I like Zelda's answer.
Edit: what I meant was, the parental status of the rabbit being referred to as "Bun-bun" in the first post, not the comic strip character.
