Bob calls in to his job..

"Hey, boss I'm not coming to work today. I'm really sick. I got a headache, stomach ache, and my legs hurt, so I'm not coming into work."
The boss says:
"You know Bob, I really need you today. When I feel like this I go to my wife, and tell her to give me sex. That makes me feel better, and I can go to work. You should try that."
2 hours later Bob calls:
"Boss, I did what you said, and I feel great! I'll be at work soon. By the way, you've got a nice house.":)
