Doofenshmirtz's Quality Bratwurst was a business Heinz Doofenshmirtz ran earlier in his life, which he described as being less evil than his current occupation. Despite the fact that bratwursts had "superior workmanship, finer meats and exotic spices", street vendors that sold hot dogs did much better than bratwurst vendors. At the present time, almost no one (other than Heinz himself) remembers that street vendors once sold bratwursts. Heinz attributes this to hot dog vendors "having it all": chrome-plated carts, endorsement deals and fancy blimps.
After two young boys walk by and make a joke about selling bratwursts being a telling sign that a person is lame, Heinz vowed that he would get revenge against the hot dog vendors. ("Backyard Aquarium") The only known worker is Heinz Doofenshmirtz, it is unknown if he was able to hire other people.
