Affirming the author's point, Burger King just added a new breakfast sandwich to their menu. In their advertising they are surprisingly open about its origins: In a new 30-second commercial from agency Crispin Porter & Bogusky, BK's mascot, the King -- armed with a flashlight and donning a hoodie -- breaks into McDonald's headquarters in the wee hours of the morning to copy the recipe for McD's Sausage McMuffin with Egg sandwich. A voice-over says, "It's not that original but it's super affordable ... egg, sausage and cheese on a toasted English muffin." http://adage.com/article?article_id=143106 http://adage.com/article?article_id=143106
