From a Wall Street Journal story by Kyle Smith headlined “‘It Ain’t Over’ Review: Yogi Berra’s Winning Words and Deeds”:

Somewhere between the sensibilities of Buddha and Mrs. Malaprop lies the quintessential Yogi Berra-ism. So appealing was the Hall of Fame catcher’s mode of expression that he joined that special category of Americans (along with Thomas Jefferson and Mark Twain) who are both quoted reverentially and credited with many aphorisms they did not actually make. Hence the waggish title of a fond and genial documentary: “It Ain’t Over.”
