Bonus Jack

The Bonus Jack is a hamburger sold by the fast-food restaurant chain Jack in the Box. It was one of the company's signature products. The Bonus Jack was first offered in 1970 to compete with McDonald's Big Mac and was discontinued in the early 1980s. The Bonus Jack has been reintroduced to Jack in the Box menus at various times throughout the years.
