Word of the Day: Wisenheimer

I've always found this word amusing. Wisenheimer was first recorded in 1904 and was popular from 1915 to 1920. According to etymonline.com, it's derived from wise (smart) + heimer, which was extracted from common surnames heard during that era. A wisenheimer is a smart aleck, as in (with a sarcastic voice) "Great joke, Lenny. You're a real wisenheimer."
