I have said things to this effect before but you really need to be careful of when you're talking to someone. It's not so important that you're mindful of the person you're talking to--whoever it is is probably an asshole anyway--but to the people who are sitting around you. For example, I just learned the method of birth control prefered by one of my coworkers. This is information I'd didn't need to know and, indeed, would rather not know.
