Guts and Balls

The difference between guts and balls can be defined as follows:

Guts: 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 cleaning or are you gonna fly off on that thing?"

Balls: arriving home late after a night out with the guys, smelling of perfurme and beer, with lipstick on your collar. Then slapping your wife on the ass and saying, "You're next."
