In honor of the upcoming 20th Anniversary of the premiere of The Simpsons, Overthinking It is devoting this entire week to a look at how America’s Favorite Family has transformed the cultural landscape. Welcome to D’OHverthinking It!

Shana Mlawski gives us ten more additions to your Simpsons vocabulary. Good ol’ rock; nothing beats that.

Jordan Stokes takes us on a tour of Simpsons musical parody over the years. If you were ever curious about the chord changes in “Dr. Zaius,” Stokes is your man.

From the guest writers, Chris Morgan guides us through the rising complexity of Springfield in his post Purple Monkey Dishwasher, and Trevor Siegler finds that he is in a Springfield, USA State of Mind.

Stay logged on for some excellent guest posts, additional Simpsons content and a very special Simpsons-related podcast on Monday morning, right after the anniversary special.
