The Thumb

So I am watching a rerun of the Big Bang Theory last night and a former beau of Penny's remarks to Sheldon, "All thumbs are fingers but not all finger are thumbs" and ever since I have been wondering.

Is there now or has there ever been a culture that did not have a special name for our opposable finger?
