Peanut

Many, many years ago at a family get together, my brother in law got my two girls together and asked them if they knew that rabbits lived in peanuts. This was news to me, I hadn't heard of this one so I hung around trying to look knowledgeable while the trick unfolded. My brother in law took a whole salted peanut and carefully pulled it apart to reveal the kernel, which to my astonishment did look like a rabbit!
