Guy calls in to work, says Boss I'm not going to be in today. I don't feel good and am achy all over.
Boss says I really need you today, when that happens to me I go to my wife and tell her I need sex. Then I feel better and can go to work.
Guy calls back and says Boss you were right, I did what you said and I'll be there in an hour. By the way you got a nice house.
