Here's the difference between having guts and having balls
GUTS- is arriving home late after a night out with the lads, being met at the staircase by your wife with a broom, and having the guts to ask.... "Are you still cleaning or are you going flying somewhere?"
BALLS - is coming home late after a night out with the lads, smelling of perfume and beer, lipstick on your collar, being met at the staircase by your wife with a broom, slapping your wife on the arse and having the balls to say..."Right...you're next."
