No English dictionary has been able to adequately explain the
difference between the two words. In a recently held linguistic
competition in London, England, attended by the best in the world,
Samsundar Balgobin, a Guyanese man from Bachelors Adventure, was the
clear winner with a standing ovation lasting over 5 minutes.
Here is his answer, in which he received an invitation to dine with
the Queen (who made a call to him after the contest).
He also won a trip to travel the world in style and a case of 25-year
old Eldorado Rum, for his answer.

The Question: How do you explain the difference between COMPLETE and
FINISHED in a way that is easy to understand? Some people say there is
no difference between the two.

Samsundar's Answer: "When you marry the right woman, you are COMPLETE.
When you marry the wrong woman, you are FINISHED. And when the right
one catches you with the wrong one, you are COMPLETELY FINISHED.
