The lab is "a fun place," the eighth-grade girls say in the article, and I utter a low growl at fun as an adjective, but let it go.
It has become a common as kudzu in Georgia, and there is nothing to be done about it except to hope that, like other vogue usages, it will eventually fade away.
My own attitude toward fun was shaped in my youth by Paul Ford in a 1965 movie, Never Too Late. The gimmick is that Ford, a middle-aged man whose grown and recently married daughter (Connie Stevens) has not succeeded in getting pregnant despite her energetic efforts with her husband, discovers that he is about to become a father again. This produces joshing from his acquaintances, chagrin from him.
His wife, played by Maureen O'Sullivan, urges him to loosen up and have some fun. Then, in his most characteristic hangdog manner, Ford says:
"Fun? Fun is when I go down to the lumberyard and the men say, 'Morning, sir,' and I say, 'Morning, men.'"
He would never have used it as an adjective.
