Toppers are notorious for only being a footnote related to the comic strip that they sit atop. That's no exception here. Little Brother ran as a topper to H.J. Tuthill's The Bungle Family, and that's the extent of the information available on it on the internet. I include it here because I don't find The Bungle Family to be that interesting, but I really like this joke.
