I can't tell if they missed the joke about losing 10 fingers and having to stop there, or if you missed their joke that you can insert the same finger multiple times as long as you only lose a bit of a finger each time.
This chain has got me wondering how we count in base 10, but we don't have 10 fingers instead 8 fingers and 2 thumbs. Maybe we have 10 digits, but digits can be fingers or toes so we really have 20 digits.
Is there a word in English which exclusively means hand-digits or fingers+thumbs or digits-toes?
