Scooby-Doo! Mystery Incorporated
Gary and Ethan disguised as Hebediah Grim targeted and attacked girls they found attractive while claiming they were indecent an impure (Velma found it annoying when the judge bluntly told her she could go free because she was dressed appropriatly when they really just didn't like her). This was becaused they wanted to impress girls by having one of them saving them when the monster was attacking. After that, they would be recognized as heros by the girls and eventually they would make up with each girl.
