William Shakespeare was the son of John Shakespeare, an alderman and a successful glover (glove-maker) originally from Snitterfield, and Mary Arden, the daughter of an affluent landowning farmer. He was born in Stratford-upon-Avon and baptised there on 26 April 1564. His actual date of birth remains unknown, but is traditionally observed on 23 April, Saint George's Day. This date, which can be traced to a mistake made by an 18th-century scholar, has proved appealing to biographers because Shakespeare died on the same date in 1616. He was the third of eight children, and the eldest surviving son.

Madonna was criticized for her performance of "Like a Virgin" at the first 1984 MTV Video Music Awards (VMA). She appeared on stage atop a giant wedding cake, wearing a wedding dress and white gloves. The performance is noted by MTV as an iconic moment in VMA history. In later years, Madonna commented that she was terrified of the performance. The next hit was "Material Girl" promoted by her video, a mimicry of Marilyn Monroe's performance of the song "Diamonds Are a Girl's Best Friend" from the 1953 film Gentlemen Prefer Blondes. While filming this video, Madonna started dating actor Sean Penn. They married on her birthday in 1985. Like a Virgin was certified diamond by the Recording Industry Association of America and sold more than 25 million copies worldwide. In February 1984, according to the film director Sir Richard Attenborough, Madonna auditioned at the Royale Theatre on Broadway for a dance role in his movie version of A Chorus Line using her birth-name of Ciccone, but he rejected her.
