Dennis Rosenlof has special sauce coursing through his veins.
"My first meal of the day is always at about 10:30, when they open up the Big Macs," Rosenlof, 64, told ABC News.
The fast-food giant McDonald's can keep its Egg McMuffins, Filets-O-Fish and all the rest of it. Rosenlof said he isn't interested.
"I enjoy what I eat," he said. "It tastes good, so I order the same thing every day."
