On the last pass my finger actually went into the chain's domain and my finger went halfway up the drive train with a chainring tooth going right through my finger nail. I couldn't just pull my finger "out" of it (it was totally stuck), so I had to actually backpedal a whole rotation to "eject" my finger.

Needless to say it hurt.
