Natural olives contain a chemical called oleuropein[0] which has a strong nasty bitter taste that renders them inedible. Soaking olives in a strong brine removes the oleuropein from the olive, turning them into the edible olive people love. Most people don't know this. It is a common prank to convince people that don't know better to eat the fruit off the tree. As the other poster said, don't do that.
