Difference Between Guts & Balls

My friend, Sunny Weathers, sent me this medical explanation of the difference between Guts and Balls...

"There 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. Medically speaking, there is no difference in the outcome; both are fatal."
