Its obviously bad manners, but some people (like my lovely #3 daughter) grin when they are embarrassed. She always grinned when we scolded her and got her fanny fanned a few times before we figured out she was not being a weizenheimer.

(She has turned out to be the most kind and compassionate person in the family I believe).
