There is, apparently, nothing more offensive to Brits than singing with one’s mouth open. Or so says the Advertising Standards Authority, which recently released data detailing complaints about commercials since the 1950s.

The most complained about ad is a 2005 spot from KFC for crispy chicken, which features some women singing with food in their mouths. The ad has received 1,671 complaints since it aired, with a commercial featuring a soccer player kicking a cat across a field coming in second with 1,313.

Is it bad? Sure. But is it offensive? Not to me. I would have gone with the cat kicking, myself.
