867-5309 Jenny was released by American rock band Tommy Tutone in 1981 and became a major hit the following year, reaching the top five in the United States. The song tells of a narrator trying to call a girl whose number he found written on a wall, and the repeated sung number turned into a real world phenomenon as fans dialled it across the country. Decades later the hook survives online as a shorthand for retro pop culture, prank calls and any joke about a number you should not call.
