On December 17, 1989, the first episode of The Simpsons hit the airwaves with "Simpsons Roasting on an Open Fire."
After more than 400 episodes and a feature-length movie later, they are now today 20 years old.
In honor of the Simpsons' 20th birthday today, I thought I'd share some of my absolute favorite moments from America's favorite family. It is absolutely impossible for me to name my favorite episodes, so I've picked a handful and thrown in lots of videos after the jump. Please add your own favorites in the comments! I also encourage you to check out this previous Simpsons diary by our Daily Kos colleague droogie6655321.
