The difference between Guts and Balls can be defined as follows:
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: "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, lipstick on your collar, slapping your wife on the ass and saying, "You're next."
