A hungry man went into a restaurant and noticed that the daily special was rabbit burgers, a real delicacy, for only 49 cents a burger. He was astounded at his good fortune to find such a bargain. When he inquired of the cook, the cook told him that in order to keep prices down he had to add some filler: in fact, only part of the burger was rabbit meat. The rest was horse meat.

“How much of each kind of meat is in a burger?” asked the customer.

The cook replied, “There is an equal amount of horse and rabbit in the burger: One horse, one rabbit.”
