Too Much Information at Work??

Okay -- what is it with people at work who feel the need to give too much personal information, or worse, get too much personal information? For example, there is a woman in my office who is CONSTANTLY trying to tell us how much her husband makes. She will never actually come out and say the number outright, but instead will say things like "he makes in 1 week what takes me 2 weeks to make", or "he received an X% raise this quarter" -- just inappropriate things.
