Step 1 : Introduction to the question "In the 1982 song by the band Tommy Tutone, what was "Jenny's" number?"
This song was released in 1981 by the band Tommy Tutone, and made the phone number 867-5309 the most famous telephone number in the world. The song also caused a fad of people dialing 867-5309 and asking for "Jenny". Its relentless chorus, “Jenny don’t change your number — eight six seven five three oh nine,” pounded the phone number into the minds of teenagers across the United States. The joke quickly became old for those who had the number. Even decades after the song dropped off the charts, people unfortunate enough to have been assigned an 867-5309 number were still getting plenty of crank calls.
