Every time I pick up my wife from work and run into her best friend, she always gives me a contemptuous look.

I was puzzled and asked my wife what was going on.
My wife said: I told her that you're impotent and I want to leave you. You hit me, and I endured it silently to stay with you.
I looked at my wife with an innocent expression.
My wife then said: Bragging about your husband to your best friend is just plain stupid.
