Joe Bloggs calls his employer and says "Sorry old chap I can't come to work today. I feel really quite ill with a headache, stomach ache, why, even my legs are painful."
"Oh dear Joe", says his employer "we are so busy today we really need you here. Why don't you try my little trick when I feel poorly.....I go to my wife and we make mad passionate love. That always does the trick and I feel so much better I can then go to work. Perhaps you should try that and see how it goes."
Two hours later Joe calls his employer. "I did what you advised and I feel so much better I think I may be able to come to work after all. By the way old chap, you do have a wonderful house."
