Skeleton's Loneliness

Alright, listen up, buttercup. This joke is so simple, it's scary... Get it? A skeleton? Scary? Anyway, the joke is that the skeleton wanted a friend because she felt "bonely", which sounds like "lonely" but uses "bone" because, well, she's a skeleton! You probably think bones are only found in your body, but you can find them in fossils, too, which are thousands or millions of years old. Bet you didn't know that!
