Frank pretends to be a burglar to prepare Laverne and Shirley self defense. He does it routinely. Edna comments she's surprised he let Laverne live with Shirley in the first place. Which brings to Shirley telling the story the time they moved in. There's a scene with Laverne and Shirley decorate the wallpaper which totally reminds me of Lucy and Ethel. It's a cute episode overall.
