The most dangerous form of skin cancer, these cancerous growths develop when unrepaired DNA damage to skin cells (most often caused by ultraviolet radiation from sunshine or tanning beds) triggers mutations (genetic defects) that lead the skin cells to multiply rapidly and form malignant tumors.
In 1978, the Broadway musical and tribute to Fats Waller, Ain't Misbehavin', received a Tony Award as Best Broadway Musical.
He had his lawyer bring him a miniature piano and spent two days in his cell writing Ain't Misbehavin'. His attorney then sold the song to a publisher for $250, enabling Fats to pay off the back alimony and get out of the jailhouse. Andy Razaf's account of the song's origin is more prosaic.
