Wiki:”Stettler went to an old Tower Records store on Broadway and handed out 5,000 flyers that read: “Guess the weight of The Fat Boys and the person who does wins 800 cans of diet Pepsi and one dollar”. Therefore, thousands of children lined up at the Tower Records store to take part. Stettler put the group members on the scale, at that time they weighed 868 pounds (394 kg). In the end, a boy from Harlem won. “
Today they wouldn’t really stand out as being that big.
