What's The Difference Between Guts And Balls?

Guts is coming home late from the bar, drunk as a skunk meeting your wife at the door with a broom in her hand and asking her if she's still cleaning the house or going out for a ride.

Balls is coming home late from the bar, drunk as a skunk with lipstick all over your face and the scent of women's perfume all over you, meeting your wife at the door and stating, "You're next, chubby."
