Star Danica McKellar has said that the writers would eavesdrop on her and Savage
to get ideas for dialogue between Winnie and Kevin.
“Kevin and Winnie’s relationship was, in some ways, defined by my friendship with Fred and some of the things that we would say,” she said. “The writers would actually take lines from things that we were saying to each other, off camera, and put it into the script.”
“There was this whole episode dedicated to, ‘Do you like him, or do you like him, like him?’ That was an expression that he and I used when we were talking about some guy that I had a crush on, in real life,” she added. “And then, it showed up in a script, a few weeks later."
