"Sardarji Selling Apples" joke

Sardarji went to US to live with his brother. Sardarji's Brother owns an apple shop in US.
One day he asked his brother to stay at the shop because he had to go somewhere.
He asked his brother if somebody comes to shop and ask for the apple's price,
tell them $2 a pound. If somebody questions whether these apples are sweet
or sour, tell them some are sweet and some are not.
If some body says I do not want to buy, tell them somebody else will buy.
Now the sardarji was ready to sell the apples.
A lady comes and asks sardarji, Do you know what time it is?
Sardarji replied $2 a pound. Lady said; all sardarji's are idiot and fools.
Sardarji replied, some are, some are not. Lady got frustrated and said, I
will take you to police station.
Sardarji replied, if you will not take me some body else will take..
