Having been in a group of drunk people who found that they had no bottle opener, and having seen what bizarre ideas they concoct to get the bottles open, I'd say a bottle opener in one's tooth merits the status of transhumanist modification.
You can open a beer bottle with your natural teeth easily enough.
These people lacked in knowledge, not in tools :-P
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
