My wife was on the rag and really acting like a pain in the ass. So I figured I throw some gas on the fire and told her: "I figured out why they call it PMS... Mad Cow Disease was already taken!"
A lady's sick of her husband's drinking, so she decides to teach him a lesson. She dresses up like Satan, and when her husband walks in from being out all night, she jumps out from behind the sofa and screams.
The guy looks at her and says, "You don't scare me. I'm married to your sister."
