The complete season 3 of Laverne & Shirley comes with four DVDs, containing six episodes each. I understand why Laverne & Shirley was spun off from Happy Days. These two girls have strong personalities. Laverne (Penny Marshall) is outspoken and often feisty, and Shirley (Cindy Williams) is naïve and optimistic.
