Lucille

In the winter of 1949, BB King played at a dance hall in Twist, Arkansas. The hall was heated by a barrel half-filled with burning kerosene, a fairly common practice at the time. During a performance, two men began to fight, knocking over the barrel and sending burning fuel across the floor. The hall burst into flames, and the building was evacuated.

Once outside, King realized that he had left his guitar inside so he went back into the burning building to retrieve his beloved $30 Gibson guitar. King learned the next day that the two men that started the fire had been fighting over a woman who worked at the hall named Lucille. King named that guitar, and every guitar he subsequently owned, Lucille, as a reminder never again to do something as stupid as run into a burning building or fight over a woman.
