Don't let bad influences in the coop.

In July 2006, BK introduced a new burger, the BK™ Stacker. Miniature laborers, known as the Stacker’s Union, were introduced in the advertisements. A television campaign promoting the Stacker’s Union was launched on July 1, 2006. Stacker posters were posted in-store and near construction sites to gain public support. At the same time, a web site of the Stackers history and traditions surfaced. Collectible Stacker figurines were made available on the site. A behind the scenes video was also posted online to create additional buzz around the characters. A Direct TV spot ran late night to promote the site.
