Why does Homer simpson constantly mocks Ned ...
What happens in Springfield stays in Springfield!
Because he is the goofy next door neighbor. Every animated series has one.
It’s Ned Flanders. Who wouldn’t mock him?
Because Ned Flanders is a mockable figure in that show.
For your entertainment.
I don’t “doodley” know for sure, but I think it’s because he is a goody-two shoes.
