ലോകത്തിലെ ഏറ്റവും ഭാരം കൂടിയ വസ്തു

Medical College Professor to a girl student :
"Which human body part expands 5 times its normal size...?"
Girl Student :
"Sir I can't answer this question,
it's too embarrassing...
Professor asked the same question to a Male Student.
Male Student :
"It's the Pupil of an human eye..."
Professor : "Correct."
Then Professor turned to the female student and said :
"Listen lady,
Not only your thinking is wrong
but
your expectations are also very high...5 times is too much"!!!
