@ossobuco,
Yes believe it or not, a well placed swear word can work wonders at the office. The thing is you cannot use it that often - only when really needed. If used often, people just take you for a someone that swears. If you don't normally swear, and you let an f-bomb rip from your mouth, you scare people.
I did this to a couple of analysts that reported to me. I was reviewing their work that was handed to me late and needed to be sent to our client. They screwed up some stuff which put me in a bad situation of trying to resolve it quickly so we could send to them on time. A big old f-bomb came out of my mouth. They looked at each other and knew they were in deep **** because I had never sworn.
Guess what - they never made that mistake again!
