Eureka, an oft-quoted expression wrongfully attributed to Aristotle, the philosopher/singer. It was in actuality his wife who coined the popular phrase.
Ari's wife often berated her husband for not bathing enough and would frequently be heard calling out: "You reek, Ari!"
Umpteen, twenty and a half times after the first such incident she tired with having to call out again, promptly shortening it to "U reek, A."
The modern version "Eureka" is a transliteration from the original Pig Latin spoken by Ari, which coincidentally was part of the reason why he stank in the first place.
It's been posited that Aristotle's infrequent bathroom breaks (BRB), with him cursing his wife's "Eureka", are the source of the false attribution.
