GUTS - is arriving home late after a night out with the guys, being met by your wife at the door, with a broom in her hand, and having the guts to ask her: "Are you still cleaning, or are you flying somewhere"

BALLS - is coming home late after a night out with the guys, smelling of perfume and beer, with lipstick on your collar and slapping your wife on the butt and having the balls to say, "You're next."


Medically speaking, there is no difference in the outcome since both ultimately result in death.
