BOGO

A Chinese guy goes into a Jewish-owned establishment to buy black bras, size 38. The Jewish store keeper, known for his skills as a negotiator, says that black bras are rare and that he is finding it very difficult to buy them from his suppliers. Therefore he has to charge $50.00 for them. The Chinese guy buys 25 pairs. He returns a few days later and this time orders fifty. The Jewish owner tells him that they have become even harder to get and charges him $60.00 each. The Chinese guy returns a month later and buys the store's remaining stock of 50, and this time for $75.00 each. The Jewish owner is somewhat puzzled by the large demand for black size 38 bras and asks the Chinese guy, "...please tell me - What do you do with all these black bras?"
The Chinese guy answers: "I cut them in half and sell them as skull caps to you Jews for $200.00 each."
