of the product, with the slogan "damn, that's a lemony cola". In addition, in a later episode, there was an old ad for Buzz Cola, stating that it has the "rejuvenating power of cocaine" in it. In the video game The Simpsons: Hit & Run, aliens Kang and Kodos use a "new and improved" Buzz Cola formula to brainwash the citizens of Springfield into performing stupid stunts for their reality TV show, Foolish Earthlings. They also dump it into the town's water supply, which reanimates the dead and creates zombies. In July 2007, 7-Eleven rebranded some stores to look like Kwik-E-Marts in select cities to promote The Simpsons Movie. Real cans of Buzz Cola were available at those locations, as well as most other 7-Elevens throughout the United States and Canada. The soda in these cans was produced by the Cott Corporation, which also makes RC Cola outside the United States. Buzz Cola first appeared in the 1984 movie Surf II.

Moe said he thought it had been banned "after all those hillbillies went blind", suggesting methanol poisoning. Lion Nathan, an Australian brewery, started to brew their own ‘Duff’ in the mid-1990s. 20th Century Fox sued, and only a few cans were produced. In the process, the beer became a collectors’ item, with one case selling for $US13,000. Duff Beer was not sold at 7-Eleven because the promoters wanted to have "good, responsible fun." However, a Duff Energy Drink was released in place of the Duff Beer. Krusty-O's Krusty-O's is a brand of breakfast cereal endorsed by Krusty the Clown which prominently features his likeness on the box. The real KrustyO's, sold by 7 Eleven, were produced by the Malt-O-Meal corporation. Krusty-Brand Cereal is the catalyst for the episode 'Round Springfield", when Bart swallows a "jagged metal Krusty-O" included in the box as a
