Was there ever any evidence that Laverne and Shirley were married?

No, there was never any evidence that Laverne and Shirley were married. The two characters were best friends who lived together in Milwaukee, Wisconsin, and worked at the Shotz Brewery. Although they often talked about their dreams of marriage and children, they never seemed to take the steps to make it happen. In fact, there were several episodes in which Laverne and Shirley discussed the idea of marriage and decided that it was not for them. They seemed to prefer the freedom of living and working together without the hassles of marriage. Laverne and Shirley also had a strong bond that seemed more like a sisterhood than a romantic relationship. The two characters were always there for each other, no matter what. They rarely had disagreements and were always there to support each other. This indicates that their relationship was more of a platonic one than a romantic one. In conclusion, there was never any evidence that Laverne and Shirley were married or in a romantic relationship.
