guts.................!

GUTS - is arriving home late after a night out with the guys, being met 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 butt
and having the balls to say: "You're next."

I hope this clears up any confusion on the definitions. Medically speaking,
there is no difference in the outcome since both ultimately result in death.
