Classic television is filled with memorable friendships, but it also has its share of legendary feuds. One of the most talked-about involved William Frawley, the actor beloved for playing Fred Mertz on I Love Lucy. While audiences enjoyed the chemistry between Fred and Ethel on screen, things behind the scenes were far less friendly. According to People, the tension reportedly lasted for years and even continued after I Love Lucy ended. By the time Frawley joined My Three Sons, his playful rivalry with former co-star Vivian Vance had become so well known that it eventually drew some of the show’s young actors into his practical jokes. A Simple Remark Sparked Years Of Tension Between William Frawley And Vivian Vance Everett Collection According to television historian Geoffrey Mark, the disagreement began during the first read-through for I Love Lucy. Vivian Vance, who reportedly did not recognize Frawley, made an offhand remark about the older actor when she learned he would play her television husband. Frawley overheard the comment and, according to Mark, never forgot it.
