Hens love roosters, geese love ganders, and everyone else loves Ned Flanders!

S4E19 “The Front”

The episode itself is where Bart and Lisa use Grampa’s name to submit their own Itchy and Scratchy episode and Homer studies to pass a test so he can finally get his high school diploma.

This scene is from the after credits “Adventures of Ned Flanders” where Ned asks his sons why they aren’t going to church. They reply that it’s because it’s Saturday.
