A Wise man sat in audience and cracked a joke.
everybody laughs like crazy...
After a moment,he cracked the same joke again.
this time less people laughed.
he cracked the same joke again and again.
When there's no laughter in the crowd.
he Smiled and said:
you can't laught at same joke again and again,but why do you keep crying over the same things over and over again ?!
