This bothered me on a number of levels, not least because I spent many hours reading Baby-Sitter's Club books growing up. I just find the idea kind of sexist that a guy can't read and enjoy books about a group of girls, especially when they are well written, at least on the scale of elementary school lit. Also, Billy would need to be a pretty precocious seven year old to reading Baby Sitter's Club books, and the general demonstrated intelligence of the family, it seems unlikely that any of them would be called precocious.

One of the better jokes I've read in a while. The set-up is not awkward, and the punchline is clever. It's a pleasant change of pace from most joke strips.

Metanote: So you might have noticed that I've fallen a little behind. Part of my philosophy of life is that there are many excuses but very few good excuses. I will say that I have been working a lot of overtime at work, but ultimately, I could have kept up if I had been more dedicated, so ultimately all I can do is apologize to any readers I might have and say that I'll try to do better. I should be able to catch up over the next day.
