The Simpsons are the highly popular characters who have been running for over 25 years. The Simpsons were created by Matt Groening, who has also created Futurama, another popular TV series.
Fafa says it will never end. and I agree.
Oddly enough, it continued after the episode "22 Short Films About Springfield," despite perfecting all of comedy with the "Steamed Hams" skit. No one knows why they bother to make more episodes. It's obvious they peaked.
