I thought #25 was missing a note (a passing note from A to F) from Auld Lang Syne.
If it was trying to trick you, it would never have though. It looks more like a test to figure out if people can hear and accept conventional (and non-conventional) chord progressions from one voice. Also, none of them seemed to have only one wrong note. They'd have several so you could pinpoint them. I'm sure if you had a II# => V => I progression, you could trick someone by changing it to ii => V => I (in other words, in C, the F# in the II# chord is substituted with an F natural).
