Unannounced Visit

A man brings his best buddy home for dinner unannounced at 6:30 after work.
His wife screams at him while his friend sits and listens in.
“My hair and makeup are not done, the house is a mess, the dishes are not done, I am still in my pajamas and I can’t be bothered with cooking tonight! Why the hell did you bring him home?”
Calmly the husband replies, “Because he’s thinking of getting married and I promised him a demo.”
