A lady was shopping for a flat TV screen when the salesman offered, "I can let you have it for $900, minus six percent for cash."
The lady was slow in math but did not want to let the salesman know that. So she told him she will think about it and come back the next day.
That night, she asked her blonde roommate, "If you were offered nine hundred dollars minus 6%, how much would you take off?"
The blonde replied, "Everything but my earrings!"
