So a few weeks ago we were hanging out with my little sister (who happens to be a very mature eight years old), and somehow the topic of "plumber’s crack" came up.

You know what plumber’s crack is; we’ve all seen it before. Someone’s pants don’t quite cover their butt crack, and it’s visible when they bend over.

My dad’s known for plumber’s crack, and my sister had noticed. Only, instead of referring to it as "plumber’s crack," she calls it the bottom line.

If that’s not priceless, I don’t know what is.
