Ea-nasir was a copper merchant in ancient Ur whose business is known from a clay complaint tablet written by a customer named Nanni around 1750 BCE. The tablet, often called the oldest customer complaint, accuses him of delivering poor-quality copper and treating messengers badly. Rediscovered in the 20th century and later popular online, Ea-nasir became a meme symbol for confident sellers of inferior goods, inspiring themed edits and sounds for bad deals.
