here is a medical distinction between Guts and Balls. We've heard
colleagues referring to people with Guts, or with Balls. Do they,
however, know the difference between them?
Here's the official distinction; straight from the British Medical
Journal: Volume 323; page 295.
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, Chubby"
I trust this clears up any confusion.
