We wouldn't joke around about the origin of this witty word. In the early 20th century, someone had the smart idea to combine the adjective "wise" (one sense of which means "insolent, smart-alecky, or fresh") with "-enheimer," playing on the pattern of family names such as "Oppenheimer" and "Guggenheimer." Of course, "wisenheimer" isn't the only “wise-" word for someone who jokes around. There's also "wiseacre," "wisecracker," "wise guy," and “wisehead.” All of these jokesters are fond of making "wisecracks."
