The babysitter and the killer upstairs — also known as the babysitter or the sitter — is an urban legend that dates back to the 1960s about a teenage girl babysitting children who receives telephone calls from a man who continually asks her to "check the children".

John Clifford, 9th Baron Clifford, (8 April 1435 – 28 March 1461), was a Lancastrian military leader during the Wars of the Roses.
 The Clifford family were one of the most prominent families among the northern English nobility of the fifteenth century; and by the marriages of his sisters John Clifford had links to some very important families of the time, including the earls of Devon.
 He was orphaned at about twenty years of age when his father was slain at the first battle of the Wars of the Roses, the Battle of St Albans in 1455.
 It was probably as a result of his father's death there that John became one of the strongest supporters of Queen Margaret of Anjou, consort of King Henry VI, who ended up as effective leader of the Lancastrian faction.
 John Clifford had already achieved prominence in the north where, as an ally of the son of the earl of Northumberland, he took part in a feud against the Neville family, the Percy's natural rivals in Yorkshire.
 This consisted of a series of armed raids, assaults and skirmishes, and included an ambush on one of the younger Nevilles' wedding party in 1453.
 Historians have seen a direct connection between his involvement in the local feud in the north with the Nevilles, and his involvement in the national struggle against the duke of York, whom the Nevilles were closely allied with in the late 1450s.
 Although this was supposedly a period of temporary peace between the factions, Clifford and his allies appear to have made numerous attempts to ambush the Neville and Yorkist lords.
Henry Clifford is a grand opera in three acts composed by Isaac Albéniz to an English libretto written by Francis Money-Coutts (under the pseudonym "Mountjoy").
 It premiered at the Gran Teatro del Liceo on 8 May 1895.
 The opera is based on historical figures and events and is set in 15th century England during the Wars of the Roses, fought between the rival houses of Lancaster and York.
 The title character, Henry Clifford, 10th Baron de Clifford, was the only son of John Clifford, a Lancastrian commander killed in the bloodiest battle of the war, the Battle of Towton, on 29 March 1461.
 Henry Clifford himself was one of the chief commanders in the Battle of Flodden against the Scots in 1513.
Charles Edward Durning (February 28, 1923 – December 24, 2012) was an American actor, with appearances in over 200 movies, television shows and plays.
 Durning's best-known roles included "The Sting" (1973) and "Dog Day Afternoon" (1975), along with the comedies "The Best Little Whorehouse in Texas" (1982), "Tootsie" (1982), and "To Be or Not to Be" (1983).
