This is now at least twice I've gotten into threads with people who are convinced the book Flipped

[conuly]

was printed tete-beche style, that is, as two books bound back to back.

This time I went ahead and emailed the author and confirmed that I am right and all those other people are wrong, it was always printed with alternating chapters. Dollars to donuts I'll now be accused of caring too much or taking this too seriously, but that won't stop me from saving the thread for future reference.
