People always think that Vivian Vance and William Frawley hated each other outside of I Love Lucy.They did dislike each other's guts, but "hate" is simply too strong a word. You don't just hate a person fully after going through the building of a phenomenal show like I Love Lucy.
Desi Arnaz and Lucille Ball ignored the two when they squabbled. The crew and the writers simply rolled their eyes whenever they see Bill and Viv wrangle and tangle. All of them knew that the quarrel meant nothing, that it was like children's hatred- childish, harmless and a waste of time. Hell, even Bill's pranks on Viv was childish. For instance, he would scare her while she was rehearsing.
In fact, Bill was a gruff character: he was Fred Mertz. His bark was worse than his bite; beneath the rough and grumpy character lay a compassionate heart. He even took care of his spinster sisters until his death.
Beneath that complicated relationship Bill and Viv shared lay a grudging respect.
We often hear this famous quote that Viv made after she heard the news of Bill's death: "Champagne for everyone!" But what many of us don't know is Vivian also said this:
"There's a great big amusing light gone out of this world."
Yes, Vivian Vance said that about William Frawley.
