There is a medical distinction. We've all heard about
people having guts or balls, but do you really know
the difference between them? In an effort to keep
you informed, the definitions are noted below:

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, fat-ass!'

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..
