Does *every* office have that one employee who just sucks the life out of everyone else?

Every office does indeed have that one person who is a life-sucker. I've found that wearing far too much cologne and griping about the latest restraining order filed against me works magic in helping them keep their distance. If all else fails, I announce that I have started selling Amway on off-hours, and ask if they would they like to hear about the latest products.
