A man tells his boss he can't come into work today bcause he has a headache. His boss replies "Do you know what I do when I get a headache? I have sex with my wife. Why don't you try it?" The next day the man comes back to work and says "Thanks for the good advice! I feel much better.

His boss says "It's no problem, glad my advice helped."

Just as he's leaving the man says "By the way, you have a nice house."
