There's a series of Jell-o pudding commercials that feature parents punishing their children for stealing it for themselves in ways that can only be described as this. One of them has a mother telling her daughter a story which is a not-so-disguised threat that she'll take her daughter's favorite things (a bike, her teddy bear) and throw them away until the girl gives her the empty containers. Another is told in nursery-rhyme style, featuring a little girl who is sent to work at a coal mine for stealing a pudding. The latter is ambiguous enough so one doesn't know if the child is merely being threatened or if she's already been sent away. There was another ad where two parents scare their children lifeless over the pudding, giving a campfire-story threat involving the "Chocobeast."
This ridiculously disturbing Skittles commercial. Makes you wonder what the suits who greenlighted this thought about what image it gave of their company...
Fun fact, the woman playing the mother there is notorious for playing abusive shrews on shows. Her most evil one? Anita from Criminal Minds episode "Mosley Lane".
All of NSPCC's ads.
An Australian charity ran a campaign trying to challenge public perception that victims of child abuse should somehow forget or "get over" the trauma as adults. It ran a PSA with a father giving a speech at his daughter's wedding about how he sexually abused her as a child, and everyone (including the bride and groom) laughing along. A radio campaign took a similar format with an athlete giving an acceptance speech thanking his abusive father for making him learn to run fast, and a woman happily reminiscing at her elderly mother's birthday party about how the mother neglected and emotionally abused her daughter.
Another NSPCC PSA showed a father abusing an animated version of his son, complete with a Wild Take or two and over-the-top reactions and pratfalls... until the end, when he throws the boy down the stairs. The real kicker is the message at the end: Real children don't bounce back.
