A massive 483 people have complained about KFC's new Zinger Crunch Salad TV advertisement which shows people singing with their mouths full of food.
Loads of mums and dads have complained the advert, where women in a call centre sing to each other while eating lunch, encourages bad table manners.
If watchdog the Advertising Standards Authority agrees with the complaints the advert could be banned.
The ad has only been on TV for a week but complaints are flooding in.
"Generally, the complainants think that the ad encourages bad manners among children, making it appear funny to speak or sing with a mouth full of food," an ASA spokeswoman said.
Two months ago KFC got into trouble with the ASA for showing a chicken fillet burger to be larger in a TV commercial than in real-life.
