not only would a combo of a big mac and a whooper proably be a true heart attack waiting to happen not to mention one would have to be crazy and want to torcher the poor fry cooks who would have to make it . but the thing  sounds like an unholy freak of a food only found in hadess but diners will never know exactly what something would be like as mcdonalds said no to burger king offer of combining the big mac and whooper. besides if any one things those two big rivals would ever team up that would be like coke and pepsi making something together. as mcds. spares the world the love child made of a big mac and whooper.
