Anyone old enough to remember Calvin and Hobbes might take it as an homage to that. (Scientific progress.)
Well, I did grow up with Calvin and Hobbes, but I am not sure why that is a reference. Is it Boink?
Those older fairy tales were products of their time, but they did not make it past Mr. Disney's sensibilities. If he had used the more gruesome versions, I dont think he would have kept the family friendly reputation. In fact, I wonder if many of those remained family friendly in their original form prior to Disney. I grew up with those tales as well from picture books, but none of them had Cinderella's sisters chipping off their toes, or other bloody events. I think parents would be rejecting them today, if not for Disney, and other similar versions.
Remember the old woman who lived in a shoe? Nursery rhymes are notoriously dark.
If I were you I'd read the book. It's hilarious, possibly intentionally so (for adults, that is).There are plenty of innocent titles that can be construed as something dirty. Like the TV show Leave it to Beaver. I guess that didn't land as an inappropriate nickname for a kid in the 1950s, when it originally aired.
Or the reading primer widely used in American schools in the same era, Dick and Jane.
