You don’t think we need skin anymore? You are pulling my leg? Right?
I do think we could get along without our baby toe and probably do better without it. I personally would give up my gall bladder and part of my stomach. But I draw the line at hair and pinky.
I might as well pull your leg. You don’t need it anymore.
If we didn't have pinkies, we'd do math in base 8, that would be a huge boon to computer designers.
