One of the kidsspeak books has a story where the kid has a calculator but no batteries, and the father has a pen but no ink, and each sells the gesheft to buy the thing the other needs.
The plot is thus identical to the O henry story where the girl has hair but no combs or something like that, etc.
The thing is though, that it really isn’t such a strange thing to happen anyway. So I’m a tad skeptical, but I ain’t ready to decide everything is made up betting on that.
