Jeremy: Throw me a rope!
Mark: I haven't got a rope.
Jeremy: What do you mean, you haven't got a rope?
Mark: I haven't got a boat, or any cattle, or anything else that would require me to own a rope. What would you do if I did have a rope?
Jeremy: Climb up it!
Mark: What with? Your "strength"?
Jeremy: OK, you could pull me up.
Mark: Oh yes, I could pull you up using my "muscles".
