There is a medical distinction between Guts and Balls.

We've all heard about people having the Guts to do something or Balls to do something. But, do you really know the difference between them?

In an effort to keep you informed, here are the definitions:

GUTS - Is arriving home late after a night out with the guys, being met by your wife who is holding a broom, and having the Guts to ask: 'Are you still cleaning, or are you flying off 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 hope this clears up any confusion on the definitions.

Medically speaking, there is no difference in the outcome.
