Laverne, Shirley and Carmine go back to Milwaukee to attend their high school reunion. What they don't know, however is that the gang back home thinks that the girls are famous movie stars and that Carmine is a famous Las Vegas singer. Lenny and Squiggy write to the gang back in Milwaukee that Carmine, Laverne and Shirley have all made it big in Hollywood. Feeling slightly insecure about how they measure up the rest of their old classmates' successes, the trio agree to go along with the story. Laverne is supposedly dating Marlon Brando and Shirley Paul Newman, when Rosie starts asking questions about Marlon and the girls start giving contradictory answers, they soon get found out. Shirley then tells the truth and Terri Buttafuco asks them to leave for lying. The girls get out the doors and Laverne comes back in telling off all her old friends for only being nice to them because they thought they were famous. This lays a heavy guilt trip on their old friends and all is forgiven.
