Guts - is arriving home late after a night out with the guys, being assaulted by your wife with a broom, and having the guts to ask:

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