The domestic pig (also swine, in some areas hog) is a large domesticated land mammal that traces its ancestry to the wild boar, and is considered a subspecies of the wild boar or a distinct species in its own right. It is likely the wild boar was domesticated as early as 13,000 BC in the Tigris River basin. Pigs are farmed for the consumption of their flesh; however, some cultures have religious dietary laws that forbid the consumption of pork, which is the name for pig meat. The animal's bones, hide, and hair have been fashioned into items such as brushes. Pigs, notably the pot-bellied pig, are also kept as pets. Miss Piggy, Babe, and Porky the Pig represent the domestic pig in entertainment and "The Three Little Pigs", Charlotte's Web, and The Sheep-Pig are prominent examples of the domestic pig in literature.

Most domestic pigs have rather sparse hair covering on their skin, although woolly coated breeds, such as the Mangalitsa, are raised.

The domestic pig is most often treated as a subspecies of its wild ancestor, the wild boar, which was given the name Sus scrofa by Carl Linnaeus in 1758, in which case its formal name is Sus scrofa domesticus.  In 1777, Johann Christian Polycarp Erxleben treated the domestic pig as a separate species from the wild boar.  He gave it the name Sus domesticus, which is still used by some taxonomists to this day.  Wild boars were in human association as early as 13,000–12,700 BC.  Escaped domestic pigs have become feral in many parts of the world (for example, New Zealand) and have caused substantial environmental damage.

Stefani Joanne Angelina Germanotta (/ˈstɛfəniː dʒʌrməˈnɑːtə/ STE-fə-nee jurr-mə-NAH-tə; born March 28, 1986), known by her stage name Lady Gaga, is an American singer and songwriter. Born and raised in New York City, she primarily studied at the Convent of the Sacred Heart and briefly attended New York University's Tisch School of the Arts before withdrawing to focus on her musical career. She began performing in the rock music scene of Manhattan's Lower East Side, and was signed with Streamline Records by the end of 2007. During her employment as a songwriter for the record company, her vocal abilities captured the attention of recording artist Akon, who signed her to his label Kon Live Distribution.

Lady Gaga came to prominence as a recording artist following the release of her debut album The Fame (2008), which was a critical and commercial success that topped charts around the world and included the international number-one singles "Just Dance" and "Poker Face". After embarking on the The Fame Ball Tour, she followed the album with The Fame Monster (2009), which spawned the worldwide hit singles "Bad Romance", "Telephone" and "Alejandro". The album's success allowed her to embark on the eighteen-month long Monster Ball Tour, which later became one of the highest-grossing concert tours of all time. Her most recent album Born This Way (2011) topped the charts of most major markets and generated more international chart-topping singles, including "Born This Way", "Judas" and "The Edge of Glory". Besides her musical career, she involves herself with humanitarian causes and LGBT activism.
