Holy crap! I knew the Simpsons was TV longest running scripted show, having been a staple on the FOX lineup for 23 seasons. It passes Gunsmoke's 20 seasons a couple years back. But what I didn't realize that Springfield's most famous yellow family is ready to air it's 500th episode Sunday night. 500 episodes! D'oh! Mmmmmmmm....
longevity....

It's not a big secret FOX's lack of popular shows back in the 90's probably helped the Simpsons stay on the air when if it was released today, if it didn't get big ratings in the first 4 shows it would have been toast. Yay early 90's FOX network crap! Take that Parker Lewis!

Here's a great article about the 500th Simpsons from Yahoo..."Fun Facts About 'The Simpsons'"
