636 is also the original area code for the fictional town of Springfield on the television series The Simpsons. In a Simpsons episode entitled "A Tale of Two Springfields", area code 939 was created for what became New Springfield after the 636 area code ran out of valid numbers. When that episode first aired in 2000, 636 was already in real-life use, but 939 would not be until 2001. In the episode "Poppa's Got a Brand New Badge" 636 was the area code for Homer's private security company.
