Today I learned that this name was actually an inside joke/reference in Godel, Escher, Bach: https://en.wikipedia.org/wiki/Etaoin_shrdlu

I definitely didn't understand at the time I read, but it's so much easier to research stuff like this now.

It was also an inside joke in Mad Magazine. I had initially thought it was Yiddish or a Don Martinism.
