I mean, it's iconic

D'oh is probably the most iconic one but "Mmm... invisible cola" and "Mmm... donuts" is actually really funny

It's kinda fun when he says "D'oh"

my fav is AHH

I like Woohoo! Why you little? and D'oh!

I also think "Boring!" is a funny one

@Th3P1an1stGam3r It doesn't sounds any funny

Like when Homer got a job in Cypress Creek and tried to convince the family to move there by putting on an advertisement video for the city

But when it started he said "Boring!" even though he wanted them to watch the video
