Got this from Catfish, it's too funny not to share.........
GUTS: Is arriving home late after a night out with the guys, being assaulted by your wife with a broom and still having the guts to say, "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 having the balls to say, "You're next!"
