Three shipwrecked men, starving, swore that each of them would cut off an arm for the others to eat. Rescue came before the last man’s turn. He had his arm taken off anyway and posted it round, so they could see he had kept his word.
A man gets a parcel in the post. Inside is a human arm. He looks it over carefully, wraps it up again and posts it to another man. The second man looks it over just as carefully, then takes it into the woods and buries it. Why?
Give me a hintThe hint
The arm came from the man who first sent it.
