Correction sky:

the above replies are sooooooooo stupid [3]

He thought that maybe people will laugh at his jokes (for a change) if he posted the same thing three times.

NO AMIT, EVEN IF YOU'D POSTED IT A 1000 TIMES, WE WOULDN'T HAVE LAUGHED

he has choice of telling 1,2,3,4,6 for speaking lie but he chooses 6 only so 1/5

it is not so that he has to speak 6 only if it comes up other number...
