A wife is nagging her husband... 'If you come back from the pub pissed again we're over. Finished'.
So the man goes to the pub, (Surprise, surprise) gets totally shitfaced, falls over and spews on himself. He tells his friends what his wife had said earlier. They said....'Simple. Put a 20 pound note in your pocket. Say someone was sick on you and they gave £20 for the dry cleaning bill'.
So the man wanders home, gets in the front door and his wife is waiting. Obviously not happy.
'No love, it's not what you think! Someone was sick on me. Look, they gave me £20 for the dry cleaning bill'.
'Why have you got two £20 notes?'
'Oh, the other one is from the bloke who shat in my pants'.
