A small girl walked into a expensive clothing store wearing a back pack on her back.
She walked up to the counter and said, "Hey mister. How much does that nice purse cost?"
The salesman glanced at the price tag and said, "This purse is rather expensive. It costs $50."
The little girl said, "I'll buy it." and reached into her back pack, pulling out a large bag.
She dumped the bags contents on the counter which resulted in a very large pile of quarters.
As she was placing them in piles of four the salesman said,
"My goodness! Did you hoard all of those quarters yourself?"
The little girl looked up from her counting and said, "No. My sister whored half of them."
