Season 9: Episode 199: Ally's F
After Ally comes home with an "F" on her report card, Debra feels she is not paying enough attention. Ray, however, feels it might be the teacher. After a small meeting, Ray goes on how Debra didn't do anything to stick up for Ally and how you should always stick up for your kids. Frank and Marie could relate to Ray's disobediance when he was in high school. But Debra finds out that Ally has a crush on Tommy Sanders, a boy in her class. When Debra confronts the teacher with this, it turns out that the teacher is a mean old bat that doesn't understand the trials kids go through.
