When Hillary's friend gets breast implants, Hillary wants them, too. Dave and Vicky are against the idea, as Dave argues that it's what you're like on the inside that counts. However, his motto is tested when he meets Larry's new girlfriend, Marla, who is overweight and not particularly attractive. As a result, Dave struggles between convincing his daughter that appearance isn't everything and telling his son he can do better.

Dave fears that the kids are getting away with far too much, and when talking to them doesn't work, he institutes a zero-tolerance, pro-spanking policy. Of course, they think he's all talk and naively call his bluff. When a humiliated Larry, the first recipient of one of Dave's spankings, moves in with Kenny, Child Protective Services is called, and it's Dave who's in for a real "spanking".
